Question

What single discount is equivalent to two successive discounts of 13% and 6%?

Hint: Let the cost be $100.

Answer 1

13% off 100 leaves you with 87.
6% off of that leaves you with 81.78

So you are looking for a discount that will give you the difference between 100 and 81.78:
x*100=(100-81.78)

Answer:18.22%
