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.
