Marcy buys a box containing 5 pizzas at the supermarket. The box of pizzas costs $24.25 and Marcy is charged an additional $1.21 in tax. She figures, with the tax, she paid $8.47 for each pizza. Estimate the cost of each pizza. Is Marcy's calculation reasonable? Select from the drop-down menus to complete the sentence.
1/5 of the price of the box of pizzas is about $4.85, and 1/5 of the tax is about $0.24. Marcy's guess that a pizza costs $8.47 is not reasonable. The cost is closer to $5.10.
