Answer:
20%
Step-by-step explanation:
Given the following;
Original price of shirt = $37.50
Amount paid = $30
Discount price = $37.50 - $30
Discount price = $7.50
Percentage saved = Discount price/Original price * 100
Percentage saved = 7.50/37.50 * 100
Percentage saved = 750/37.50
percentage saved = 20%
Hence the percentage saved is 20%
