Answer: b. $22.75

Step-by-step 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, y=mx+c , m= cost per topping  and c= cost of pizza without any topping.

From the given information.

c= $14

Function of cost becomes = y=mx+14

For x= 2 and y= 17.50, we have

17.50=m(2)+14

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

m=\$ 1.75  [Divide both sides by 2]

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

y=1.75x+14

Now, for x= 5

y=1.75(5)+14=8.75+14=22.75

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