Answer:
The number of ways are 40320.
Step-by-step explanation:
Consider the provided information.
Ms. Smith keeps eight different cookbooks on a shelf in one of her kitchen cabinets.
We need to determine the number of different ways to put eight cookbooks on the shelf.
We need to select 8 cookbooks taking 8 at a time.
So use the permutation formula:
Substitute n=8 and simplify.

Hence, the number of ways are 40320.
It would be 3.87,to the nearest hundred cause the real length is √15
40*52= 2080
34840 / 2080 = $16.75 an hour
