 Math Central Quandaries & Queries
 A t-shirt is on sell at 33 1/3% off. Joey paid $12 for his shirt. What was the original price? Hi, 33 1/3% is the fraction 1/3 so the t-shirt sale was one third off. There was one third off and hence Joe paid two thirds of the original price. Hence$12 is two thirds of the original price and thus $6 is one third of the original price. If$6 is one third of the original price then the original price must have been $18. Check: Original price$18.
33 1/3% of $18 is 3 of$18 which is $6. Joe paid$18 - $6 =$12

There is a more algebraic wy to solve this problem. Let $P be the original price then since Joe paid two thirds of the original price 2/3 ×$P = $12 Multiply both sides by 3 to get 2 ×$P = $36 divide both sides by 2 and you get$P = \$18

I hope this helps,
Penny
