EXAMPLE 3 Standardized Test Practice The parks and recreation department in your town offers a season pass for $90. • As a season pass holder, you pay $4 per session to use the town’s tennis courts. • Without the season pass, you pay $13 per session to use the tennis courts.

EXAMPLE 3 Standardized Test Practice Which system of equations can be used to find the number x of sessions of tennis after which the total cost y with a season pass, including the cost of the pass, is the same as the total cost without a season pass? y = 13x y = 4x A y = 4x y = 90 + 13x B y = 13x y = 90 + 4x C y = 90 + 4x y = 90 + 13x D

EXAMPLE 3 Standardized Test Practice SOLUTION Write a system of equations where y is the total cost (in dollars) for x sessions. EQUATION 1 y = 13 x
