Answer 2

Answer: b. $22.75

Explanation:

Given : A large pizza with no toppings costs $14.00. A large pizza with 2 toppings costs $17.50.

Let x denotes the number of toppings and y be the cost of that pizza.

Then, , m= cost per topping and c= cost of pizza without any topping.

From the given information.

c= $14

Function of cost becomes =

For x= 2 and y= 17.50, we have

tex]3.50=m(2)[/tex] [Subtract 14 from both sides]

[Divide both sides by 2]

For c= 14 and m =1.75 , our function becomes.

Now, for x= 5

Hence, the cost of a pizza with 5 toppings = $22.75
