The expression 8x - 55 gives the cost of a day spent at the aquarium for 8 people with a $55 discount. Find the cost of a day spent at the amusement park for tickets that cost $9 each if x represents the price per ticket.

y = 8x - 55
x = 9
y = 8(9) - 55
y = 72 - 55
y = 17
A day spent at the park costs $17
