Answer:
$373.43
Step-by-step explanation:
the cash outflows associated to the first loan are 5 level payments of $2,504.56 each (= $10,000 / 3.992717 PV annuity factor, 8%, 5 periods).
the cash outflows associated to the second loan are 5 level payments of $3,707.47 each (= $15,000 / 4.048857 PV annuity factor, 7.5%, 5 periods).
total cash outflows associated to both loans = $6,212.03
inflows associated with investment are 4 level payments of $7,632.20 each (= $25,000 / 3.275596 PV annuity factor, 8.5%, 4 periods).
net cash flow year 1 = $7,632.20 - $6,212.03 = $1,420.17
net cash flow year 2 = $7,632.20 - $6,212.03 + ($1,420.17 x 1.06) = $2,925.55
net cash flow year 3 = $7,632.20 - $6,212.03 + ($2,925.55 x 1.06) = $4,521.25
net cash flow year 4 = $7,632.20 - $6,212.03 + ($4,521.25 x 1.06) = $6,212.70
net cash flow year 5 = ($6,212.70 x 1.06) - $6,212.03 = $373.43
