STEP 1:
Sale Price= Cost - (Cost * Discount %)
Sale Price= $80 - (80 * 10%)
=80 - 8
=$72 sale price
STEP 2:
use sale price from step 1 in this equation
Final Price= Cost + (Cost * Tax %)
Final Price= $72 + (72 * 7%)
= 72 + 5.04
= $77.04
ANSWER: The final price after a 10% discount and 7% sale tax is $77.04.
