Percy buys tomatoes that cost $0.58 per pound. He pays $2.03 for the tomatoes, How many pounds of tomatoes does he buy?

MArishka [77]

Since each pound casts $0.58 and the total spent is $2.03, you divide 2.03 by .58 to find the total amount of pounds.
2.03/.58=203/58=3.5
Therefore, Percy bought 3.5 pounds of tomatoes.
