Brad buys a jacket that is on sale for 30% off the original price. The expression p- 0.3p can be used to find the sale price of the jacket, where p is the original price of the jacket. If the original price of the jacket is $80, what is the sale price?

$56

Step-by-step explanation:

First, let me show you how the expression for the sakes price was derived.

Let the Original Price of the Jacket =p

30% of the price of the jacket = 30% X p = 30/100 X p= 0.3p

Sales Price= Original Price -Discount

=p-0.3p

If the Original Price, p =$80

Sales Price = p-0.3p

=80- (80 X 0.3)

=80 - 24

=$56

The sales price of the jacket is $56.

expression #3 is not equivalent. the others are.

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）
