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? select all that apply

Answer 1

Given:

Coupon = 20% off = 0.2 of purchase price before discount

Purchase before the discount = $68

Discount = 0.2(68) = $13.6

Let T represent total cost after discount.

The equation to represent this scenario is:

`T\text{ = 68 - }0.2(68)\text{ }`
`T\text{ = 68(1 - 0.2)}`

ANSWER:

T = 68 - 0.2(68)

T = 68(1 - 0.2)
