First you would want to find the original price. to do this you need to find the multiple. 1) start with 100 if it's an increase, add if it's a decrease, subtract in this case we want to add to find the original price. 100 +33.33%= 133.33 then divide by 100 = 1.33 this is the multiplier $66 x 1.33= $87.78 $87.78 -$66 = $21.78 So the answer to the question is $21.78 Hope this helped Xx
