- Convert future to present and then solve for G using P/G factor:
6000(P/F,15%,4) = 2000(P/A,15%,4) – G(P/G,15%,4)
6000(0.5718) = 2000(2.8550) – G(3.7864)

- Find A in year 1 and then find next value.
900,000 = A{1 – [(1+0.05)5/(1+0.15)5}]}/(0.15 – 0.05)
900,000 = A{3.6546)
A = $246,263 in year 1
Cost in year 2 = 246,263(1.05)

2.48 Decrease deposit in year 4 by 5% per year for three years to get back to year 1.
First deposit = 1250/(1 + 0.05)3

- Simple: Total interest = (0.12)(15) = 180%
Compound: 1.8 = (1 + i)15
i = 4.0%
