Question

The table shows the cost for ordering a certain number of pizzas, What is the value of x if the cost is proportional to the number of pizzas ordered? Show your work and unit rate! (6 Points) 5 Pizzas Ordered Cost 2 $19.98 4 $39.96 $29.97 X

Answer 1

First we can calculate the cost for one pizza, it can be calculated if we divide the cost of 2 pizzas between 2

$1\text{ pizza cost =}\frac{19.98}{2}=9.99$

In order to know the value of x we will multiply the cost for one pizza by the quantity of pizza ordered in this case 5

x=9.99*(5)=49.95

If I ordered 5 pizzas I will pay $49.95

x=49.95
