To find the number of toppings chosen for a total cost of $13.50, we can plug the total cost into the function and solve for x.
f(x) = 0.75x + 9
13.50 = 0.75x + 9
4.50 = 0.75x
x = 6
Therefore, the number of toppings chosen for a total cost of $13.50 was 6 toppings.
Apply the linear function f(x)=.75x+9 to the following context. A large cheese pizza costs $9, and each additional topping costs $0.75. In this function, x represents the number of toppings that you choose to put on your pizza. Determine the number of toppings you chose to put on your pizza if the total was $13.50.
