student received a coupon for 19​% off the total purchase price at a clothing store. Let c 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.

1 answer

The expression for the new price of the purchase after applying the coupon is:
c - 0.19c

To combine like terms, we simplify the expression:
c(1 - 0.19) = c(0.81)

Therefore, an equivalent expression by combining like terms is:
0.81c
