Question

The price of a pizza is $7.99 with an additional $1.35 for each topping. Write a function rule that gives the total price as a function of the number of toppings x.

a) P(x)= 7.99+1.35x
b) P(x)= 1.35+7.99x
c) P(x)= 7.99x+1.35
d) P(x)= 1.35x+7.99

Answer 1

The correct function rule for the total price of a pizza based on the number of toppings is P(x) = 7.99 + 1.35x.

Step-by-step explanation:

The function rule that gives the total price as a function of the number of toppings x is P(x)= 7.99+1.35x. This formula represents a linear function where the base price of a pizza without toppings is $7.99 and the price increases by $1.35 for each additional topping a customer chooses. So, for example, if a customer wants three toppings, the function would be calculated as P(3) = 7.99 + 1.35(3).
