Question

A 5-pound bag of apples costs $3.50. At the

same rate, what would be the cost of 7
pounds of apples?

Answer 1

x = $4.90

Explanation:

Let x represent the cost of 7 pounds of apples

5/3.50 = 7/x <----- (Cross multiplying to solve )

(FRACTION ABOVE)

5x = 7 * 3.50

x = $4.90

Answer 2

3.50 is the cost of a 5 pound bag of apples. 1 pound bag is $.07 — .07 • 5 = 3.50. So them at means .7 • 7 = $4.90
