For this case, the first thing we must do is define variables.
We have then:
x: cost of each bag of popcorn
y: cost of each drink
writing the system of equations we have:
9x + 9y = 117
x + 3y = 23
Solving the system of equations we have:
x = 8 $
y = 5 $

English = 4 (For girls)
<u><em>Total for Science:</em></u>
12+7 = 19
<u><em>Total for English:</em></u>
25 + English + 19 = 70
