Domino’s pizza is delicious. The company’s success is proof that people enjoy their pies. The company is also tech savvy: you can order online, and they even have a pizza tracker so you can keep tabs on your delivery!
The website is great. But one thing it’s not is transparent. Domino’s does not tell you how much the component pieces cost; they only tell you an item’s final price after you build it. In the launch activity of Domino Effect, students use linear equations to find the base price (y-intercept) and cost per additional topping (slope). Let’s find out how much Domino’s is really charging for pizza.
Students explore this even further in the project tasks, and can choose between three topics. In one task, students research another pizza restaurant’s pricing scheme and mathematically compare it to Domino’s. In another, they use percent change to compare the increase in price between Domino’s pizza sizes to the increase in toppings. In still one more task, they investigate why Domino’s pricing scheme is so weird. How many toppings do most people order, anyway?
