Your brother has saved $60 to spend on basketball cards he plans to by the cards at a sale single card is $9 and if u buy three cards u get a forth for $7 if u buy five cards the cost is $39.50 what is the greatest number of cards your brother can get for $60.

7 cards.

Step-by-step explanation:

60-39.5=20.5, that's what he has left if he buys 5 cards.

so, if you buy 2 more cards, that would be 18 dollars so 20.5-18=2.5

5 cards+ 2 cards= 7 cards.

He still hzs 2.5 dollars left
