Hello! I can help you with this! So there is a $95 guitar for 15% off. That means Ms. Shelton would still have to pay 85% of the $95. To find the new sale price of the guitar, let’s multiply. 95 * 0.85 is 80.75. $80.75 is the new sale price of the guitar. However, not let’s add the sales tax to find the total price of the guitar. Multiply by 1.065 or 106.5%, because hat would give you all of the total price. 80.75 * 1.065 is 85.998 and other numbers behind it or 86.00 when rounded to the nearest hundredth. The total price Ms. Shelton will pay for the guitar is $86.
