The MP3 player Nicky purchased was marked 20% off the original price. At the register, the clerk took 48$ off the original price. What was the original price of the MP3 player?
48$ must be 20% of the original cost. In math, whenever you see the word "is," think "equals." Also, whenever you see "of," think multiplication.
20% of the original cost is 48$.
0.20 times the original cost = 48$
0.20(original cost) = 48
original cost = (48)/(0.20)
original cost = $240
