Cory purchased a frying pan which was on sale for 30% off. She saved $3.75 along with the sale. What was the original price of the frying pan?
Use a proportion to ?nd out the original cost of the frying pan; part/whole = % /100. The $3.75 which was saved is part of the original price. The whole price is what we are looking for, so call it x. The % is 30 (the percent off); 3.75 /x = 30/100. To solve the proportion, cross-multiply. (3.75)(100) = 30x. Divide both sides by 30 to solve for x; 375/30 = 30x/30; x= $12.50.
