Example Question #164 : Percentage
Katy buys jeans that is on sale for $84. The tag says that the price was originally $142. What discount is she receiving on the shirt? Round to the nearest tenth of a percent.
None of the other answer options.
Use proportions and cross-multiply to find the percentage of the cost that she is paying, then subtract that answer from the original price to solve for the discount.
If she is paying 59.2% of the regular cost, then subtract that figure from 100%.
100% - 59.2% = 40.8%
You could also set up the proportion so that you could arrive at the answer after cross-multiplying by subtracting 84 from 142 as the first step.
