Combine standard function types arithmetically to create models.

Combine two functions by addition or subtraction in context

Problem

Resale value is \(V(n)=2000(0.8)^n~\text{dollars}\) and accumulated maintenance is \(M(n)=50n~\text{dollars}\) after \(n~\text{service}~\text{intervals}\). Build \(N(n)=V(n)-M(n)\), give its nonnegative input domain, and interpret the resulting net value and units.
