Question

A function that can be used to model the cost of producing x t-shirts is c(x)= 10 + 7x, and the function that can be used to model the amount of money to be made from selling x t-shirts is m(x) = 20x.
Write a function p(x) to represent the total profit of selling x number of shirts.

Answer 1

Hey!

Hope this helps....

~~~~~~~~~~~~~~~~~~~~~~~~

f(x) = 20x - (10 + 7x)

f(x) = 13x - 10

This is because we want to take the Selling Price minus the Production Price, which will allow us to get the Profit...

Hope this Helps!

Answer 2

P(x) = amount made - cost
p(x) = 20x-7x-10
p(x) = 13x -10
