At an auction, a painting sold for $148 500. This was 135% of what it sold for 3 years ago. What was the selling price of the painting 3 years ago? Justify your answer.
Answer: $110,000 =================================== If $148,500 is 135% of the original price, you need to find 100/135 of it. (Divide it by 135 to find 1% then multiply it to a hundred to find 100%)
