Question

James spent $(2y2 + 6). He bought notebooks that each cost $(y2 − 1).

The expression to find the number of notebooks James bought is .

If y = 3, James bought notebooks.

Answer 1

First, divide the total cost by the unit cost:

(2y^2 + 6) / (y^2 - 1)

Then, if y = 3, just plug in and compute.

I know you can do that!
