That one has me stumped too! It seems some people are good with numbers, while others are good with words. And a few are good with both.
Ryan was given $100 to shop with by his grandmother. He shopped in a store where he gets a 40% employee discount. What is the retail amount he can purchase with his $100?
The $100 becomes 60% of the total merchandise value (100%-40% discount).
The inverse (1/x) of .60 (60%) = 1.6667. Thus, the total value of the merchandise = $166.67.
