Question

During a sale, a store manager reduces a sweater's price by 30%. After the sale, the manager increases the price by 30%. Are the prices before and after the sale equal?

Answer 1

example:
sweater cost $20.00 - 30% = $14.00
$14.00 + 30% = $4.2 total of 18.20
no cause the sale price was lower when adding on 30%

Answer 2

give the sweater any initial price to show whether they are equal
sweater initially = $10
decrease by 30% = $7
increase $7 by 30% = $9.10
No, they are not equal.
