Question

A student received a coupon for 13​% off the total purchase price at a clothing store. Let b 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. b−0.13​

Answer 1

0.87b

Use the Distributive Property to combine like terms. Remember that when there is no number in front of a variable it is understood that the variable has a coefficient of 1

Answer 2

Price after 13% off = b x (1-0.13)

Explanation:

Original price of the purchase = b

Discount on total purchase = 13%= 0.13

Price after 13% off = b x (1-0.13)
