Question

At a movie theater adult tickets cost $10, and child tickets cost $6. Which equation can be

used to find s, the total number of dollars a family of k adults and 5 children would pay for
movie tickets?

A-s = 10k + 6(5)

B-S = 6k + 10(5)
C-S = (10 + 6)· (k + 5)

D-s = 10k - 6(5)

Answer 1

Answer: Choice A

s = 10k + 6(5)

========================================================

Reason:

k = number of adults

10k = cost for all the adults (at $10 per ticket)

5 = number of children

6(5) = cost for all the children ($6 per ticket)

10k + 6(5) = total cost for all adults and children

s = total cost in dollars

s = 10k+6(5)
