Question

A book store sells a textbook for $150. If the textbook is on sale with 12% off, and there is a sales tax of 8.25% added to the price of the textbook, what is the final price of the textbook, including sales tax? Round your answer to the nearest cent.

Answer 1

The textbook is $150 originally, so to find the price of the textbook on sale, multiply the original price by 12% (0.12). Then subtract 12% of 150 from 150.

• 150 * 0.12 = 18

Subtract 18 from 150.

• 150 - 18 = 132

Multiply the price of the textbook on sale by the sales tax of 8.25% (0.0825). Then add the tax price onto the sale price of the textbook.

• 132 * 0.0825 = 10.89

Add 10.89 to 132.

• 132 + 10.89 = 142.89

The final price of the textbook is $142.89.
