Each game at a carnival costs $0.50, or you can pay $15 and play an unlimited amount of games. Write and solve an inequality to find how many times you should play a game so that the unlimited game play is less expensive than paying each time. Interpret the solution.

Inequality: 0.50x ≥ 15

x ≥ 30

The solution of x ≥ 30 means that if you play a game more than 30 times, then the unlimited game play option is less expensive than paying each time.
