Question

Ellen used a coupon at a restaurant for a certain percent discount of the meal. What percent discount did she receive?

Answer 1

The question is not clear, but it is assumed that the discount is a rate previously established on the coupon. This can be 10%, 15%, 20%, 25%, etc. For this reason no calculations are made to determine the relationship between what is requested in the question and what Ellen could actually receive as a benefit.
