The admission fee at a movie theater is $2.50 for children and $7.00 for adults. On a certain day, 2100 people enter the theater

alexdok [17]

Make two equations
C = children, A = adults
2.50C + 7.00A = 7950
(C + A = 2100) * 2.5
2.50C + 2.50A = 5250
Use elimination
4.5A = 2700, A = 600
2100 - 600 = 1500
Solution: 600 adults, 1500 children

Dominik [7]

Answer: There are 312 people who named neither blue nor red as their favorite color.

Step-by-step explanation:

Since we have given that

Total number of people who are surveyed = 7

Number of people who named blue as their favorite color = 4

According to question, one out of three named 'red'.

So, Out of seven people , number of people who named neither blue nor red as their favorite color is given by

$7-(4+1)=7-5=2$

There if there are 1092 people who were included in the survey , then we need to find the number of people who named neither blue nor red as their favorite color.

$\frac{2}{7}=\frac{x}{1092}\\\\x=\frac{2\times 1092}{7}\\\\x=312$
