Answer:

The final cost will be $44.22

Step-by-step explanation:

First we must find the cost of the book after the discount. We can do this by multiplying the original cost by 92% (since it is 8% off)

$44.50 * 92% = $40.94

Now we need to find the sales tax price. So we multiply by 108% (the cost + 8% tax).

$40.94 * 108% = $44.22
