Let I be the purchase value of an equipment and V(t) be the value after it has been used for t years. The value V(t) depreciates at a rate given by differential equation ‌

dv(t)

=−k(T−t), where k>0 is a constant and T is the total life in years of the equipment. Then the scrap value V(T) of the equipment is
