Problema Solution

Papa John's charges a fixed amount for pizza plus an additional amount per topping. One day Mr. Friday paid $9 for a pizza with two toppings. Another day he paid $15 for a pizza with six toppings. Determine the linear function that describes the price of pizza in terms of the number toppings.

Answer provided by our tutors

we have these two points: (2, 9) and (6, 15)


we solve for the linear equation:


y-9 = [(15-9)/(6-2)] (x-2)

y = 1.5x + 6
