Question

A student received a coupon for 20% off the total purchase price at a clothing store. Let y be the

original price of the purchase. Use the expression below for the new price of the purchase. Write
an equivalent expression by combining like terms.
y-0.2y​

Answer 1

Answer: 0.8y

Explanation:

Original price of purchase = y

Since the received a coupon for 20% off the total purchase price at a clothing store, the expression for the new price will be:

= y - (20% × y)

= y - (0.2 × y)

= y - 0.2y

= 0.8y

The equivalent expression is 0.8y.
