A large cheese pizza costs $18. Each topping you add on costs $1.50. Write an expression for how much it would cost to get a large cheese pizza with x toppings added.

Answer:

1.50c +18

Step-by-step explanation:

The constant price is 18 dollars, which never changes and for every topping you get, it costs $ 1.50. Since we don't know how many extra toppings are added we write 1.50c. This shows that the price will be determined by the number of extra toppings added. If you got no toppings, sub in 0 for c to get $ 18 .
