Step-by-step explanation:

Mario bought 3 cans of tennis balls. Mario paid for part of the purchase that he made using a gift card with $7.25 on it. He paid for the rest with $4.72 of his own money. This means that total cost of his purchase (3 cans of tennis balls). Total cost of the 3 cans of tennis balls will be

Amount on gift card + cash amount

= 7.25 + 4.72 = $11.97

Therefore, 3 cans of tennis balls cost $11.97

The unit cost, C of one tennis ball will be

Total cost of 3 cans of tennis balls / total number of cans of tennis balls bought.

C = 11.97/3 = 3.99

C (x) = 3.99x

Where x is the number of cups of tennis
