Question

A 5-pound bag of apples cost $3.50. Use that rate, to complete the table to identify equivalent ratios, and then answer the questions.

Apples ? 5 *? 15
Cost 0.70 3.50 7 ?

Answer 1

I just had this question and I didn't get it either :(

Answer 2

Set up a proportion. 3.50 over 5 = x over 1 (x is what we are trying to find= the cost of 1 lb of apples)

Use cross products and multiply 3.50 by 1 to get 3.50 and then divide that by 5 to get 0.7.

So the apple cost 0.7 or seventy cents per pound.

Check: 0.7*5=3.5
