Answer:
The two pizzas will same cost when 2 toppings are added on the pizza.
Step-by-step explanation:
We are given the following in the question:
Papa's pizza:
Cost of pizza = $6.80
Cost of each topping = $0.90
Let x be the total number of toppings.
Total cost =
![c_1(x) = 6.80 + 0.90x](https://tex.z-dn.net/?f=c_1%28x%29%20%3D%206.80%20%2B%200.90x)
Little Italy's pizza:
Cost of pizza = $7.30
Cost of each topping = $0.65
Let x be the total number of toppings.
Total cost =
![c_2(x) = 7.30 + 0.65x](https://tex.z-dn.net/?f=c_2%28x%29%20%3D%207.30%20%2B%200.65x)
Equating the two equations, we get,
![6.80+0,90x = 7.30 + 0.65x\\\Rightarrow 0.25x = 0.5\\\Rightarrow x = 2](https://tex.z-dn.net/?f=6.80%2B0%2C90x%20%3D%207.30%20%2B%200.65x%5C%5C%5CRightarrow%200.25x%20%3D%200.5%5C%5C%5CRightarrow%20x%20%3D%202)
Thus, the two pizzas will same cost when 2 toppings are added on the pizza.
