Answer:

$0.80 per notebook

$0.40 per pencil

Step-by-step 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 = [tex] \frac{3.20}{4} = 0.80 [/tex]

Rate = $0.80 per notebook

Given that,

12 pencils = $4.80

The cost of 1 notebook/rate = [tex] \frac{4.80}{12} = 0.40 [/tex]

Rate = $0.40 per pencil.
