2.1 1. (F/P,8%25) = 6.8485; 2. (P/A,3%,8) = 7.0197; 3. (P/G,9%,20) = 61.7770;
4. (F/A,15%,18)= 75.8364; 5. (A/P,30%,15) = 0.30598

2.2 P = 140,000(F/P,7%,4)
=140,000(1.3108)
= $183,512

2.3 F = 200,000(F/P,10%,3)
= 200,000(1.3310)= $266,200

2.4 P = 600,000(P/F,12%,4)
= 600,000(0.6355)
= $381,300

2.5 (a) A = 225,000(A/P,15%,4)
= 225,000(0.35027)= $78,811

(b) Recall amount = 78,811/0.10
= $788,110 per year

2.6 F = 150,000(F/P,18%,7)
= 150,000(3.1855)
=$477,825

2.7 P = 75(P/F,18%,2)
= 75(0.7182)
= $53.865 million

2.8 P = 100,000((P/F,12%,2)
= 100,000(0.7972)
= $79,720

2.9 F =1,700,000(F/P,18%,1)
= 1,700,000(1.18)
= $2,006,000

2.10 P = 162,000(P/F,12%,6)
= 162,000(0.5066)
= $82,069

2.11 P = 125,000(P/F,14%,5)= 125,000(0.5149)
= $ 64,925

2.12 P = 9000(P/F,10%,2) + 8000(P/F,10%,3) + 5000(P/F,10%,5)
= 9000(0.8264) + 8000(0.7513) + 5000(0.6209)
= $16,553

2.13 P= 1,250,000(0.10)(P/F,8%,2) + 500,000(0.10)(P/F,8%,5)
= 125,000(0.8573) + 50,000(0.6806)
= $141,193

2.14 F = 65,000(F/P,4%,5)
= 65,000(1.2167)= $79,086

2.15 P = 75,000(P/A,20%,3)
= 75,000(2.1065)
= $157,988

2.16 A = 1.8(A/P,12%,6)
= 1.8(0.24323)
= $437,814
