I REALLY NEED HELP! WILL MARK BRAINIEST!! follow up questions in the comments An office copier has an initial price of $2,100. A service contract costs $200 for the first year and increases $30 per year thereafter. It can be shown that the total cost of the copier after n years is given by C(n)=2,100+185n+15n^2.
The average cost per year for n years is given by b. C(n)=C(n)/n

1. Find the rational function of b. C(n)=C(n)/n
