I NEED HELP ON THIS CONSTRUCTED RESPONSE QUESTION! :(
zavuch27 [327]

Answer:


Step-by-step explanation:

She bought 18 ride tickets at $0.75 per ticket, so she spent 18 * $0.75 = $13.50 on rides. She spent a total of $33.50 for only admission and rides.

$33.50 - $13.50 = $20

Admission is $20.

(a) Let y represent total cost. Let x represent the number of ride tickets.

(b) y = 0.75x + 20

(c) The total cost is the cost of x ride tickets plus the admission.

x ride tickets cost 0.75x.

Admission is a fixed 20.

Adding the cost of ride tickets, 0.75x, to the admission cost, 20, gives you the total cost, y.
