Asweater is on sale for 20% off the regular price. the sale price is $60. what is the regular price of the sweater?

The answer is B

If the sweater is on sale for 20%, then the sale price will be 80% of the regular price.

Therefore, $60 = 80% of regular price

$60/80 = $0.75 which gives you 1% of the regular price
So $0.75 is 1% of regular price.

$0.75 * 100 = $75 which gives you the regular price as 1% multiplied 100 times = full price

S, full price is b.) $75
