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, , 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
