A tire company determines that to manufacture a certain type of tire, it costs $9000 to set up the production process. Each tire that is produced costs $21 in material and labor. The company sells this tire to wholesale distributors for $49 each.
(a) Find a linear function C that models the total cost
of producing x tires.
I got 9000+21x
(b) Find a linear function R that models the revenue
from selling x tires.
Also not sure
(c) Find a linear function P that models the profit P(x) from selling x tires. [Note: profit = revenue − cost.]
