EXAMPLE 3 Standardized Test Practice As a season pass holder, you pay $5 per game to use the towns golf course. Without the season pass, you pay $10 per game to use the golf course. The parks and recreation department in your town offers a season pass for $30.

3
EXAMPLE 3 Standardized Test Practice Which system of equations can be used to find the number x of games of golf 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 = 10x y = 5x A y = 10x y = 30 + 5x C y = 5x y = 30 + 10x B y = 30 + 5x y = 30 + 10x D

4
SOLUTION EXAMPLE 3 Standardized Test Practice Write a system of equations where y is the total cost (in dollars) for x games. EQUATION 1 y = 10 x Game (dollars per game) Game (dollars per game) Games

5
EXAMPLE 3 Standardized Test Practice EQUATION 2 y = 30 + 5 x ANSWER The correct answer is C. A C B D Games (cost per game) Games (cost per game) Games

6
GUIDED PRACTICE for Example 3 4. Solve the linear system using the graphing method. Find the number of games after which the total cost with a season pass, including the cost of the pass, is the same as the total cost without a season pass.

7
Games Dollars

8
GUIDED PRACTICE for Example 3 Label the axiss Label the individual graphs Circle the solution point ANSWER 6 games

9
GUIDED PRACTICE for Example 3 5. Is it better to buy the season pass or not ? It is better to buy the season pass if you intend to play more than 6 games. If you think you will only play 5 games or less it is better to not buy the season pass.
