Alocal movie theater offers a special deal for birthday parties. the price, which covers the cost of the tickets and a box lunch, includes a flat fee of $75 plus $5 per ticket. sarah’s parents spent $150 all together at the theater to celebrate her birthday. which equation can be used to determine how many children, x, were in the group?

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
