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
Soooo, full price is b.) $75
