Question

Mike is shopping for new clothes. He has a coupon for 20% off of his total purchase. His purchase price before the discount is $68. Let T represent the total cost after the discount. Which equation can be written to model this scenario?

Answer 1

Given that the cost before discount is $68 and the discount is 20% then the discount is

= 20% * $68

the cost after discount is the amount left when the discount is subtracted from the original cost. If this is T the

T = $68 - (20% * $68)
