Gabriella's school is selling tickets to a choral performance. On the first day of ticket sales the
school sold 14 senior citizen tickets and 14 child tickets for a total of $252. The school took in
$154 on the second day by selling 9 senior citizen tickets and 7 child tiekets. Find the price of a
senior citizen ticket and the price of a child ticket.
The ticket price of
A Senior citizen = $14
A Child = $4
First day of ticket sales :
Senior citizen tickets (s) = 14
Child tickets (c) = 14
Total price of both tickets = $252
14s + 14c = 252 eq. (1)
Second day of ticket sales :
Senior citizen tickets (s) = 9
Child tickets (c) = 7
Total price of both tickets = $154
9s + 7c = 154 eq. (2)
Multiplying equation 2 with 2, we get
18s + 14c = 308 eq. (3)
Now, we will subtract eq. (1) from eq. (3)
18s + 14c = 308 eq. (3)
-14s - 14c = -252 eq. (1)
____________________
4s = 56
s = 56/4
s = 14
We get the ticket price of one senior citizen which is 14 Dollars.
Now, we will put s = 14 in eq. 2,
So, 9s + 7c = 154
(9×14) + 7c = 154
7c = 154 - 126
c = 28 / 7
c = 4
Ticket price of one child is 4 Dollars.
Hence, the ticket price of a senior citizen and a child is $14 and $4, respectively.

ALGAE A scientist has a fish tank in the shape of a rectangular prism. The tank is 18 inches high, 14 inches wide, and 30 inches long. After one month, the scientist found that the sides and bottom of his fish tank were covered with algae. The scientist wants to run tests on the algae to help determine why it started to grow. How much algae is there for the scientist to test?
the algae that is present with the scientist to research upon covers a surface area of 2004 inches² in the rectangular prism.
The dimensions of the rectangular prism is given by:
Height = h = 18 inches
Width = w = 14 inches
Length = l = 30 inches
Now, we have to calculate the surface area of the tank excluding the top of the tank to find out how much algae has been present there for the scientist to test.
So, the formula for surface area will become:
A = 2(w l + h l + h w) - l w ( as the top has to be excluded)
Now substituting the values of l, w and h, we get that:
A = 2 [ (14) (30) + (18) (30) + (18) (14) ] - (30) (14) inches²
A = 2 [ 420 + 540 + 252 ] - 420 inches²
A = 2 [ 1212 ] - 420 inches²
A = 2424 - 420 inches²
A = 2004 inches²
Therefore, we get that, the algae that is present with the scientist to research upon covers a surface area of 2004 inches² in the rectangular prism.

If the coordinates of the point a is (2,1) and midpoint is (0.-3), then the coordinates of b is (-2,-7).
Midpoint:
Midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints.
The formula for midpoint is,
[tex](x_{m},y_{m})= (\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2} )[/tex]
Where
(x₁,y₁) is the coordinates of the first point and
(x₂,y₂) is the coordinates of the second point
and
[tex](x_m,y_m)[/tex] is the mid point of the first and second points.
Given,
Mid point = (0,-3)
Point a = (2,1)
Here we need to find the point b.
Let (x,y) be the point of b.

An empty shipping box weighs 250 grams. The box is then filled with t-shirts. Each t-shirt weighs 132.5 grams.
The equation W=250+132.5t represents the relationship between the quantities in this situation, where W is the weight, in grams, of the filled box and is the number of shirts in the box.
If the company ships 100 t-shirts in a box, how much will the box weigh?
________ grams
========================================================
Explanation:
t = number of t-shirts
t = 100 shirts are in the box
Plug this into the equation and simplify to find W
W = 250+132.5t
W = 250+132.5(100)
W = 250+13250
W = 13500
The box weighs 13500 grams
This is equivalent to 13500/1000 = 13.5 kg
What’s the domain and range ??
USE INTERVAL NOTATION.
Only answer if you know!
Domain: (-∞, ∞)
Range: (-∞, ∞)
Step-by-step explanation:Domain and range help us describe the values a graph covers.
Defining Domain and Range
The domain is defined as all the x-values included in a function.The range is defined as all of the y-values included in a function.Remember that the x-values are along the horizontal axis, and the y-values are on the vertical axis.
The function given to us extends infinitely to the left and right as shown by the arrows. Additionally, the graph extends up and down infinitely; thus the range is also infinite.
Interval Notation
Interval notation should be written as (minimum value, maximum value). If the minimum and maximum values are included within the range or domain, then the parentheses should be replaced with brackets. This looks like [included minimum, included maximum]. Since a function cannot actually include infinity, an infinity symbol should never have brackets.
Eventually, this linear function will reach every single x and y-value in existence. So, both axes have a minimum of -∞ and a maximum of ∞. Thus, both the domain and range are (-∞, ∞).
Hint for future problems: all linear functions will have a domain and range of (-∞, ∞).

Step-by-step explanation:
I would suggest starting with 1 and working to 4, as it is set up for you like that.
I would start by writing down what you know, then what you need as follows:
[tex]Givens:\\ C_{ost}=13x+50;\\ R_{evenue}=36x;\\P_{rofit}=R_{evenue}-C_{ost};\\ x=N_{umber\ of\ animals}\\[/tex]
[tex]Find:\\1.\ Profit\ equation\\2a.\ C_{ost}\ to\ make\ 70\ animals\\2b.\ P_{rofit}\ from\ selling\ 70\ animals\\3a.\ C_{ost}\ to\ make\ 100\ animals\\3b.\ P_{rofit}\ from\ selling\ 100\ animals\\4.\ N_{umber}\ of\ animals\ needed\ to\ produce\ P_{rofit}\ of\ \$1100[/tex]
Now you can read it easier. Given that Profit is Revenue minus Cost, plug the equations for Cost and Revenue into the Profit equation as follows:
[tex]P_{rofit}=36x-(13x+50)\\NOTE:\ Do\ NOT\ forget\ to\ put\ the\ C_{ost}\ equation\ in\ parenthesis\ as\ you\ \\must\ subtract\ the\ entire\ C_{ost}.\\\\Distribute\ the\ negative:\ P_{rofit}=36x-13x-50\\Combine\ like\ terms:\ P_{rofit}=13x-50[/tex]
With the Profit equation, it is now easier to solve 2b, 3b, and 4.
[tex]C_{ost}\ for\ 70: C_{ost}=13(70)+50=(700+210)+50\\NOTE:\ I\ used\ the\ fact\ that\ 13*70=(10+3)*70=10*70+3*70\\C_{ost}=910+50=960\\This\ could\ also\ be\ written\ more\ clearly\ as\ C_{ost}(70)=960\\\\P_{rofit}(70) = 13(70)-50\\P_{rofit}(70)=(700+210)-50\\P_{rofit}(70)=910-50\\P_{rofit}(70)=860\\\\C_{ost}(100)=13(100)+50\\C_{ost}(100)=(1300)+50\\C_{ost}(100)=1350\\\\P_{rofit}(100)=13(100)-50\\P_{rofit}(100)=(1300)-50\\P_{rofit}(100)=1250\\[/tex]
Problem 4 will involve using the (now) known amount for profit, $1100 to find the unknown number of animals. This will involve a little bit more "algebra" compared to the prior questions.
[tex]P_{rofit}(x)=1100=13x-50\\1100=13x-50\\[/tex]
Because 13x - 50 is 1100, 13x will be 1100 + 50, just as
[tex]5*2+10 = 20\\5*2=20-10\\[/tex]
So, add 50 to both sides:
[tex]1100+50=13x-50+50\\1150=13x\\[/tex]
Because 13x is 1150, x will be 1150÷13, just as
[tex]5*2=10\\5=\frac{10}{2}[/tex]
So, divide 13 from both sides:
[tex]\frac{1150}{13}=\frac{13x}{13}\\\\\frac{1150}{13}=x[/tex]
Because 1150/13 is not an integer, use a calculator, or simplify the improper fraction to obtain...
x=88.5 (Approximately)

89. Philip solved the following problem incorrectly. Explain his mistake.
1659
x 21
1659
+3318
4977
Philip's mistake is he did not add zero at ten's place.
When the multiplication is performed with two or more digits in the bottom number, zeroes are added as per the position. We see that in number 21, one is at one's place and 2 is at ten's place. Hence, when multiplying the digit 2 with the number 1659, we will add zero at one's place.
Performing the correct multiplication -
1659
× 21
1659
+33180
The result of multiplication will be the sum of numbers 1659 and 33180.
Result = 34,839
Therefore, the multiplication of the numbers will give result 34,839. Hence, the mistake is not keeping zero at one's place, while performing multiplication.
