Unit 3: Evaluating Consumer Decisions with Math
☆Introduction
Have you ever wondered if that "BOGO 50%" deal is really worth it? Or if the name brand is actually better than the store brand? Whether you are comparing prices, checking reviews, or just looking for the best value, you should take a second to think about the math behind it before jumping into a deal!
This unit is all about become a better shopper, and seeing how good other people are with their choices. You will learn how to use simple math to compare products, analyze deals, and make smart financial decisions that make the most sense. By the end of the unit, you'll feel more confident using math that are good for you!

This article provides examples of how math concepts are applied in everyday shopping scenarios. It covers topics like calculating discounts, comparing unit prices, and total cost calculations.
👕Scenario: BOGO & Discounted T-Shirts
Jessica is shopping for new t-shirts for this summer. She is trying to decide which store to buy from to get the best deal. Assume that each store has the same t-shirts. Look at the deals below to help her decide.
Store A:
$30/T-shirt
Buy One Get One Free Sale
Store B:
$30/T-Shirt 40% off sale
Calculate and Decide:
Which store should Jessica shop at if she wanted to buy 2 t-shirts?
What if Jessica wanted to buy 3 shirts? Would her decision change?
🍿Scenario: Popcorn
You know those Smartfood popcorn bags that some of you probably like to eat? For those of you that do enjoy eating them... How do you bring it to school? Do you have those individual baggies that are already packed for you, or do you have to put some in a zip lock bag? Lets compare the two.
What purchase is the smarter financial choice?
Take a look at the price, but that shouldn't be all you look at. We have to look at how much we're getting for that price. If we get the large bag, how much do we have to get a container for it (zip lock bags, reusable, etc.)?
Calculate & Discuss:
- Which is the better overall financial decision?
- Is there any reason that someone may choose the option that is not necessarily the best financial decision? Explain.
