Answer:
$189.00
Step-by-step explanation:
Using the total cost of the shoes before tax, but after the sale price and coupon were applied, $74.50, first add back the $20 discount from the coupon:
74.50 + 20.00 = 94.50
Then, add the new amount by itself to find the original price since the sale applied a 50% discount:
94.50 + 94.50 = $189.00
