There are two choices for pizza available. There are 2 7-inch pizzas for $2 each. There is one 12-inch pizza for $4.
Zach says 2 7-inch pizzas are better because you get more pizza for the same price. Lucy says the 12-inch pizza is a better deal. Who is right? Explain.
Lucy, answers vary
(Because if you measure the whole circle of the pizza the 12 inch pizza is more food.
