Presentation transcript:

Percents of Change and Percents of Percents For the following situation, choose which you think is the best deal:

A store is offering the choice between two sale options for a $100 pair of jeans: The jeans are already on a 60% off sale. The clerk offers to give you a coupon that allows you to take an additional 5% off the original price (making it a 65% off sale). OR The clerk also offers to give you a 10% off coupon that would apply after the original 60% was taken off.

Answer 60% off of $100 = $40, so both options start at $40. Option A: you would actually be taking 65% off of $100 (or in other words, you would be finding a 65% decrease in $100). This leaves $35 Option B: you would actually be taking 10% off of $40 (or in other words, you would be finding a 10% decrease in $40). This leaves $36. Option A is a better deal!
