Onur is participating in a walkathon fundraiser. Two donors promised to donate money based on the total distance he walks. The money, A , in dollars, that he receives from the first donor given that he walks d kilometers is given by the formula A ( d ) = 10d. The money, B , in dollars, that he receives from the second donor given that he walks d kilometers is given by the formula B ( d ) = 2 d + d 2. Let T be the total money that Onur raises from those donors by walking d kilometers in the walkathon.
