A cоmpаny prоduces twо different bаsebаll bats, a tapered handle bat and a non-tapered handle bat. If t represents the number of tapered handled bats and n represents the number of non-tapered handle bats, then 220t + 145n + 100 describes the revenue from sales of the two types of bats. The polynomial 140t + 110n + 310 describes the cost of producing the two types of bats. If the company produces and sells [a] non-tapered handled bats and [b] tapered bats in one month, what is the company's net profit or loss in dollars for the month?
