It costs $13 to order a cheese pizza and $2 for each extra topping. Write an equation for the function that gives the total cost y in dollars for ordering a pizza with x extra toppings. Using the equation from question 5. Complete the table.
Extra Toppings X Total Cost (S) Y: Blank, blank, blank
3
4
5

y = 2x + 13

Step-by-step explanation:

total cost of pizza (y) = price of cheese pizza + price ($2) of each added topping (x)

we can start by looking at y = 13 the total cost (y) of a CHEESE pizza is $13

If you want to ADD additional toppings, you pay $2 for each topping. We know how much each topping is, but we are not sure how many additional toppings we need. So x will represent how many toppings are added. We can multiply $2 times how many toppings to figure out the additional cost of the toppings.

y = 13 + 2x ; remember, function form is y=mx+b so re-write the equation as

y = 2x + 13

I am unsure why the 3, 4, and 5 are listed here, but if the problem is asking you to solve for how much your pizza will cost with 3 toppings, 4 toppings, and 5 toppings, you will need to use substitution to solve for the cost.

y = 2x + 13

y = 2(3) + 13

y = 6 + 13

y = 19

If you order a pizza with three additional toppings, your total cost will be $19.

the answer is b.6
