1. T-Shirt Question
Suppose you decide to sell commemorative t-shirts at your town’s centennial picnic. You know you can make a tidy profit, but only if you can sell most of your supply of shirts, because your supplier will not buy them back.
How many shirts can you reasonably plan on selling?
Discuss any questions that come up because of this question-the idea is that you have to do some form of data collection in order to figure out how many shirts and what sizes you will sell.
