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 ? Apples cost $ __ per pound.

Answer 1

0.70 per pound.

Answer 2

Cost 0.70 per pound.

Explanation:

If you see the cost and the weight you can get the price per pound, so if 5 pounds cost $3.50, you can evaluate doing a rule of three:

`(3.50)/(5)=(x)/(1)`

So if you clear X you´d get this:

`x=((3.5)(1))/(5)`

`x=0.70`

So the cost per pound is $0.70.

Now that you have the cost per pound you can do the equivalent ratios:

Cost---------------Apples

0.70---------------1 pound

3.5--------------- 5 pounds

7--------------- 10 pounds
