Question

Notebooks are priced 3.20 for 4 notebooks Pencils are priced 4.80 for 12 pencils, write a rate

Answer 1

$0.80 per notebook

$0.40 per pencil

Explanation:

To find the rate, we need to determine how much each item costs. That is, the cost per item.

Given that,

4 notebooks = $3.20

The cost of 1 notebook/rate =
`(3.20)/(4) = 0.80`

Rate = $0.80 per notebook

Given that,

12 pencils = $4.80

The cost of 1 notebook/rate =
`(4.80)/(12) = 0.40`

Rate = $0.40 per pencil.
