Answer:
-1764
Step-by-step explanation:
Given the cost of investment = $28000
Annual cash flow = $5600
Time period = 6 years
Salvage value = $3300
Interest rate = 10%
Net gain from the investment and its present value = Annuity (P/A, r, n) + Salvage value (P/F, r, n) - investment
= 5600 (P/A, 10%, 6) + 3300 (P/F, 10%, 6) - 28000
= 5600 x 4.355 + 3300 x 0.56 - 28000
= -1764
