Kathi and Robert Hawn had a pottery stand at the annual Skippack Craft Fair. They sold some of their pottery at the original price of $13.50 each, but later decreased the price of each by $4.00. If they sold all 91 pieces and took in $972.50, find how many they sold at the original price and how many they sold at the reduced price.
The number sold at the original price is 27 and they sold 64 at the reduced price.
How to calculate the value?Let x = number of pieces sold at 13.50
Let y = number of pieces sold at 9.50
The equation will be:
x + y = 91. ..... i
13.50x + 9.50y = 972.50 ..... ii
From equation i x = 91 - y
13.50x + 9.50y = 972.50
13.50(91 - y) + 9.50y = 972.50
1228.50 - 13.50y + 9.50y = 972.50
1228.50 - 4y = 972.50
4y = 1228.50 - 972.50
4y = 256
y = 256/4
y = 64
Since x + y = 91
x = 91 - 64 = 27
Therefore, the number sold at the original price is 27 and they sold 64 at the reduced price.

the inequality always, sometimes, or never true
4x8> 1 + 4(x + 3)
The given inequality is never true which means it has no solutions. If an inequality has no actual solution, then there aren't any numbers that might be used to solve it and make the statement true. An inequality can be made true by substituting any real number into it if the solution to the inequality is all real numbers.
Given the expression is 4x ₋ 8 > 1 ₊ 4(x₊3)
first apply the distributive property.
4x ₋ 8 > 1 ₊ 4x ₊ 12
now combine the like terms.
4x ₋ 8 > 4x ₊ 13

Answer: 410 possible points
To solve for the possible points in the course, use a proportion and cross multiply.
What is a proportion?
A proportion is two fractions that are equal to each other. For the fractions to be equal, they are proportionate. In our math problem, percentage is proportionate the the number of points.
The fractions represent information you have, and one variable will represent what you are solving for.
GivenYour points = 361
Points to get an 'A' = your points + 8
'A' = 90% of possible points
Find the points needed for an 'A' at 90%Points to get an 'A' = your points + 8
= 361 + 8
= 369
State variableslet x be the amount of possible points
Write a proportionWe know the number of points for 90% is 369 points. Remember that 90% is the same as 90/100.
Keep the information with the same units inside the same fraction. Here, percentage is represented by the first fraction. Points is represented by the second fraction.
[tex]\displaystyle{\frac{90}{100}=\frac{369}{x}}[/tex]
SolveWe can solve using cross multiplication. This is when we multiply each numerator by the denominator from the other fraction.
[tex]90x = 369*100[/tex] Simplify by multiplying.
[tex]90x = 36,900[/tex] Isolate the variable x.
[tex]\displaystyle{\frac{90x}{90} = \frac{36,900}{90}}[/tex] Divide both sides by 90 to cancel out 90 on the left.

Bill's school is selling tickets to a fall musical.
On the first day of ticket sales the school sold 1 adult ticket
and 6 child tickets for a total of $52.
The school took in $66 on the second day by selling 1 adult
ticket and 8 child tickets.
Find the price of an adult ticket.
•$3
•$10
•$7
•$9
By solving a system of equations, we can see that the adult ticket costs $10.
How to find the price of the adult ticket?
Let's define the two variables:
x = price of the adult ticket.y = price of the child ticket.With the given information, we can write a system of equations:
1*x + 6*y = $52
1*x + 8*y = $66
By taking the difference between the two equations we get:
(1*x + 8*y) - (1*x + 6*y) = $66 - $52
2y = $14
y = $14/2 = $7
Now that we know the value of y, we can find the value of x.
Replacing the value of y in the first equation we get:
1*x + 6*$7 = $52
x = $52 - 6*$7 = $10
With this, we know that the adult ticket costs $10.

The area of the rectangular garden in terms of a function in x is given by 44x - x²sq. ft.
What is the area of a rectangle?
A rectangle is a closed geometric figure with opposite sides equal to each other. The area of this rectangle is given by the product of its length and width.
Calculating the area of a rectangular garden in terms of a function in x
Let us consider a variable x that denotes the length of a rectangular garden
Given perimeter of a rectangular garden is 88 ft with y as the width of a rectangular garden
Perimeter = 2×(length + breadth)
88 = 2(x + y)
44 = x + y
y = 44 - x
Area of a rectangular garden = xy
= x(44 - x)
= 44x - x² sq. ft
Hence, the area of a rectangular garden in terms of a function in x is given by 44x - x² sq. ft.

Landon was making snacks for his family for the week. He used 25/35 of a pound of peanuts. Additionally he use 1/7 of a pound of almonds. At the end of the week, he determined that 3/5 of the snacks were leftover. At the end of the week, how much snacks, in pounds, was used?
Landon used an amount of 4 / 7 of a pound of snacks for his family of the week.
How to estimate the amount of snacks spent per week
In this problem we must determine the total amount of snacks used by Landon in a period of a week, which is found by the summing fractions. Then, we must solve the following linear equation:
(3 / 5) · x = x - 25 / 35 - 1 / 7
(3 / 5) · x = x - 25 / 35 - 5 / 35
(3 / 5) · x = x - 20 / 35
x - (3 / 5) · x = 20 / 35
(2 / 5) · x = 20 / 35
7 · x = 10
x = 10 / 7
And the amount of snack used is determined by the following subtraction:
z = (2 / 5) · (10 / 7)
z = 20 /35
z = 4 / 7
Landon used an amount of 4 / 7 of a pound of snacks for his family of the week.
