Craig went bowling with $25 to spend. He rented shoes for $5.25 and paid $4.00 for each game. What was the greatest number of games Craig could have played?
Set up the cost function C(g) where g is the number of games Craig plays:
C(g) = Game fee * number of games (g) + shoe rental fee
C(g) = 4g + 5.25
The problem asks for the maximum number of games Craig can play for $25. So we want an inequality of less than or equal to.
4g + 5.25 <= 25
Type this inequality into our search engine, and we get:
g <= 4.9375
We want exact games, so we round this down to 4 games.
