Answer:
Explanation:
The cost of the three books that James bought from the bookstore.
He has a coupon for 25% off the original price. This means that the amount by which the original price was reduced would be
25/100 × 39.99 = 0.25 × 39.99 = $9.8325
The cost of the books would be
39.99 - 9.8325 = $30.1575
He is charged 8.5% sales tax. This means that the amount paid for tax would be
8.5/100 × 30.1575 = 0.085 × 30.1575 = $2.56
the total cost of his purchase would be
2.56 + 30.1575 = $32.7175
