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 $\frac{{dV\left( t \right)}}{{dt}} = - k\left( {T - t} \right)$ where $k > 0$ is a constant and $T$ is the total life in years of the equipement. Then the scrap value $V(T)$ of the equipment is
