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

2. 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.

3. 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!
