Answer 2

a)

$2.79 per pound.

$0.93 per apple.

b)

Unit price per pound is typically used because weight and size of every apple is not same.

Explanation:

5 pound bag of organic apples = $13.95

1 pound bag of organic apples = $13.95/5

= $2.79

The unit price of apples that cost $13.95 for 5 pounds is $12.79 per pound.

As a general rule, 1 pound of apples is equal to: 4 small apples. 3 medium apples. 2 large apples. So, here we assume that apples are of medium size.

3 apples cost = $2.79

The unit price means 'what is the cost of 1 apple'

1 apple cost =$2.79/3

=$0.93

The unit price of apples that cost $2.79 for 3apples is $0.93 per apple.
