Find the unknown quantities, assuming economic equivalence () among each pair of cash flows. i is effective interest rate.

(e) 2000 P= ? 1500 i = 10%/period 1000 500 0 1 2 3 4 0 1 2 3 Careful about properly using Linear Gradient P = 1000 A4 = ? Geometric gradient i = g = 10%/period A3 Az A. + 2 + 3 0 1 2 4 0 1 2 3 (8) A = 1000 B? B? B? i = 10%/period 1 0 1 2 3 3 4 4 0 1 2 Make both equivalent to a present value first
