15 Alex purchased two cars for $15,000 and $17,000. The life for both the cars is 5 years and the operating costs are $7,000 and $5,000, respectively. Determine the incremental cash flows .for the given cars : 2) Extra investment = $+32,000 and annual incremental cash flow (5 years) = $-12,000 Extra investment = $-2,000 and annual incremental cash flow (5 years) = $+2,000 Extra investment = $-8,000 and annual incremental cash flow (5 O years) = $-12,000 Extra investment = $400 and annual incremental cash flow (5 O years) = $400 14 A $10,000 municipal bond due in 10 years pays interest of $400 every 6 months. If an investor purchases the bond now for $9000 and holds it to maturity, the rate of return received can be determined by the following equation ) (2 ) PIA,1,20) +)400 + 10,000- = 0 (10,000(P/F,1,20 PIA,i,10) +)800 + 9000- = 0 (10,000(P/F,i,10 P/A,i,10) +)400 + 9000- = 0 (10,000(P/F,i,10 P/A,1,20) +)400 + 9000- = 0 (10,000(P/F,1,20
