Fund A accumulates at the force of interest tA=1+0.05t0.05 at time t0. Fund B accumulates at the constant force of interest B=0.05, for t0. Suppose the initial investments, the investment at time t=0, to Funds A is 1000 and to Fund B is 500 . There is a third fund, Fund C, whose amount at time t is equal to the amounts in Fund A plus Fund B at any time t0. If Fund C accumulates at the force of interest t, for t0, find an expression for t
