1. Below are the prices for a medium 2-topping pizza, and a medium 4-topping pizza from Domino's. How much do you think Domino's is charging for each topping, and how much would you expect to pay for a plain cheese pizza?
For each topping - $1.49 For the regular cheese pizza - $10.99
2. Write an equation you could use to determine the price of a pizza for a given number of toppings. Then graph it. If you ordered your favorite medium pizza, how much would you expect to spend?
Equation: 10.99 + 1.49x = T
Our favorite pizza which has 2 toppings would be $13.97
Equation: 10.99 + 1.49(2) = 13.97
3. If you double the number of toppings that you order, do you pay twice as much for the pizza? Why or Why not?
No, the price of the pizza is not doubled, because the whole pizza is not doubled. Only the toppings or $1.49 is doubled. If one topping is ordered the 1.49 + 10.99 dollars = the price of the pizza in total, but the doubled price of the toppings makes: 2.89 + 10.99.
4. Write an equation for the price of a small Domino's pizza, and an equation for the price of a large Domino's pizza. Of the three sizes, which has the highest cost per topping, and why might this be? The lowest base price?
Equations for small pizza:9.49 + 0.5x = T
Equations for large pizza: 3.666 + 1.014x = t
