Question

Arianna bought 4 notebooks for $9. 0. What is the cost per notebook?

Answer 1

`c=2.25`

Explanation:

To find the cost per notebook we simply have to find the unit cost.

Formula to calculate the unit cost:


`(price)/(quantity) =c`
Substitute and solve:

`(9)/(4) =9/4=2.25`

`c=2.25`

Therefore 1 notebook costs 2.25$.

I hope this helps.
