Which expression represents the new price?

B 0.6p D 1.6p
Answer:
The cost per child is $9
Step-by-step explanation:
x + 3y = 40
2x + 3y = 53
x = 40 - 3y
2(40-3y) + 3y = 53
80 -6y + 3y = 53
80 - 3y = 53
-3y = 53 - 80
-3y = -27 (divide both sides by -3)
y = 9
This means that the cost per child is $9
Now solve for x
x = 40 - 3y
x = 40 - 3 (9)
x = 40 - 27
x = 13
Cost per parent is $13.
