This activity opens with a scenario in which a rack of clothing, originally on sale for thirty percent off the original price, has been discounted by an additional fifty percent. Students are challenged to determine if the new price is actually eighty percent of the original price. The activity, part of the Figure This! collection of 80 real world math challenges, demonstrates that understanding percentages is important for making decisions based upon survey results, interest rates, and medical reports. The Hint suggests that students begin their calculations with an item that costs one hundred dollars. Multiple approaches to the problem are given in the solution. Related questions ask students to calculate percentages for additional price reductions. Answers to all questions and additional resource suggestions are provided.
