Answer 2

Answer: $21.42

Explanation:

First we must REDUCE the price by 15%.

But what is 15% of $24.00?

Well:

24 × .15 = 3.6

15% off of $24.00 means $3.60 off of $24.00

$24.00 - $3.60 = $20.40

The book is $20.40 on sale.

Next we must ADD 5% sales tax.

But what is 5% of $20.40?

Well:

20.4 × .05 = 1.02

$1.02 is 5% of $20.40

$20.40 + $1.02 = $21.42
