Rachel is ordering pizza. tony’s pizza charges $7 for a large cheese pizza plus $0.75 for each additional topping. maria’s pizza charges $8 for a large pizza plus $0.50 for each additional topping. for what number of toppings will the cost of a large pizza be the same at either restaurant?

let no. of toppings = x

cost of tony's ppizza = 7 + 0.75x

cost of maria's pizza = 8 + 0.5x

according to question:

8 + .5x = 7+ .75x

=> 0.25x = 1

=> x = 4

no this is a nonlinear negative

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
