Answer:
Francisco/Franceska made 110 dollars.
Step-by-step explanation:
$8/hr- less than 5yrs
$6/hr- more than 5yrs
10hrs- 2yr old=$80
5hrs- 8yr old= $30
30+80= $110 this week
Answer:
$110
Step-by-step explanation:
Ages 5 and younger- $8
Ages over 5- $6
2 year old-10 hrs= 10x$8=$80
8 year old-5 hrs= 5x$6=$30

Jillian’s school is selling tickets for a play. The tickets cost $10.50 for adults and $3.75 for students. The ticket sales for opening night totaled $2071.50. The equation 10.50 a plus 3.75 b equals 2071.50, where a is the number of adult tickets sold and b is the number of student tickets sold, can be used to find the number of adult and student tickets. If 82 students attended, how may adult tickets were sold? adult tickets
Answer:
168 adult tickets
Step-by-step explanation:
3.75(82) (82 students)
307.5
2071.5 - 307.5 ( you subtract since you only need to know the number of adults)
1764
1764/10.5 (you divide since each adult is 10.5$)
168
The number of adult tickets sold was 168.
Given that, the tickets cost $10.50 for adults and $3.75 for students. The ticket sales for opening night totaled $2071.50.
Total number of students =82
What is the system of equations?In algebra, a system of equations comprises two or more equations and seeks common solutions to the equations. "A system of linear equations is a set of equations which are satisfied by the same set of variables."
a is the number of adult tickets sold and b is the number of student tickets sold.
Now, 10.50a+3.75b=2071.50
Put b=82 in the equation 10.50a+3.75b=2071.50 and simplify.
10.50a+3.75×82 =2071.50
⇒10.50a+3.75×82 =2071.50
⇒10.50a+307.5 =2071.50
⇒10.50a=1,764
⇒a=168
Therefore, the number of adult tickets sold was 168.

Bowl B1 contains two white chips, bowl B2 con-tains two red chips, bowl B3 contains two white and two red chips, and bowl B4 contains three white chips and one red chip. The probabilities of selecting bowl B1, B2, B3, or B4 are 1/2, 1/4, 1/8, and 1/8, respectively. A bowl is selected using these probabilities and a chip is then drawn at random. Find (a) P(W), the probability of drawing a white chip. P(B1 I W), the conditional probability that bowl B1 had been selected, given that a white chip was drawn.
Answer:
By using law of total probability:
P(W) = ∑i P(Bi ) P(W/Bi)
=1/2 .1 + 1/4 .0 + 1/8 .1/2 + 1/8 .3/4
=1/2 + 0 + 1/16 + 3/32
= 21/32
= 0.656
Step-by-step explanation:
B1 contains = two white chips
B2 contain = 2 red chips
B3 contain = 2 white and 2 red chips
B4 contains = 3 white chips and 1 red chips
P(B1) = 1/2
P(B2) = 1/4
P(B3) = 1/8
P(B4) = 1/8
Probability of drawing white chips:
P(W / B1) = 2. 1/2 = 1
P(W/B2) = 0/2 = 0
P(W/B3) = 2/4 = 2
P(W/B4) =3/4
By using law of total probability:
P(W) = ∑i P(Bi ) P(W/Bi)
=1/2 .1 + 1/4 .0 + 1/8 .1/2 + 1/8 .3/4
=1/2 + 0 + 1/16 + 3/32
= 21/32
= 0.656
I don't understand these 2 problems, can someone help me please
Answer:
32 servings of cake
Step-by-step explanation:
so you are trying to figure out how much cake you can make if each box makes 12 servings
you have 8 eggs
2 cups of oil
4 boxes of cake mix
unlimited water
so each box needs 1/3 cup of oil, 3 eggs, and 1 cup of water.
you only have enough eggs to make 2 and 2/3 boxes of cake.
this means that you can make 32 servings of cake.

Calculate the sum of the infinite series 72+60+50+125/3+...
The sum of the given infinite series is 432.
The given infinite series is 72+60+50+125/3+.......
What is the sum of the infinite series formula?The general formula for finding the sum of an infinite geometric series is S=a/r-1, where s is the sum, a1 is the first term of the series, and r is the common ratio.
From the series a=72 and r=60/72 =5/6
So, sum = [tex]\frac{72}{1-\frac{5}{6} }[/tex]
= [tex]\frac{72}{\frac{1}{6} }[/tex]
= 72×6
= 432
Hence, the sum of the given infinite series is 432.
