Let:
x = the number of games Bucky can bowl
y = the total price
y = 2.50x + 4
(The total price is equal to the price of each game times the number of games plus the cost to rent a pair of shoes)
> If Bucky has $20 how many games can he bowl?
y = 20, solve for x
20 = 2.50x + 4
16 = 2.50x
x = 6.4
Bucky can play 6 games (not 6.4 because he can't play 0.4 of a game and not 7 because then it will cost over $20)
