Question

Ralph sold brownies for ​$0.66 a piece in order to earn money to buy baseball cards. If the cards cost ​$0..90 per​ pack, and if Ralph had no money left over after buying​ them, what is the least number of brownies he must have​ sold?

Show method for answer if possible?

Answer 1

he would have to sell at least 2 brownies because then he would have more than $.90

If he only sold one he wouldn't have enough money, he also can't sell part of a brownie
