If the cash flow on the left is disaggregated into an annuity and two single cash flow as shown on the right. What would be the value for a, b, and c in the equation to calculate the equivalent future worth (F) of the cash flow? 1) a = ? ; 2) b = ?; 3) c = ? (first box for a; second box for b; third box for c. Please only enter numbers as your answer.) F = ? $3,700 $3,700 $3,700 $3,700 $8,700 0 $4,300 $3,700 $3,700 $3,700 1 2 3 4 lo 1 2 3 4 5 $8,700 $600 $20,000 lo 2 3 4 5 F = $3,700(F/A,8%,a)(F/P,8%,b) - $20,000(F/P,8%,5) +$600(F/P,8%,c) + $8,700 $20,000
