Multiple Choice

Suppose you bring $40 to the county fair, and you buy ride tickets and game tickets. The ticket prices are as follows:

•$5 for rides; and

•$4 for games

Which equation relates the number of tickets for rides, r; the number of tickets for games, g; and the total amount of money you have to spend, in dollars?

• 4r + 5g = 40

• 5r + 4g = 40

• 40 + 5r = 4g

• g = 40 - 4r
