2.1 (1) (P/F, 6%, 8) = 0.6274
(2) (A/P, 10%,10) = 0.16275
(3) (A/G,15%,20) = 5.3651
(4) (A/F,2%,30) = 0.02465
(5) (P/G,35%,15) = 7.5974
2.2 P = 21,300(P/A,10%,5)
= 21,300(3.7908)
= $80,744
2.3 Cost now = 142(0.60)
= $85.20
Present worth at regular cost = 142(P/F,10%,2)
= 142(0.8264)
= $117.35
Present worth of savings = 117.35 – 85.20
= $32.15
2.4 F = 100,000(F/P,10%,3) + 885,000
= 100,000(1.3310) + 885,000
= $1,018,100
2.5 F = 50,000(F/P,6%,14)
= 50,000(2.2609)
= $113,045

2.6 F = 1,900,000(F/P,15%,3)
F = 1,900,000(1.5209)
= $2,889,710
2.7 A = 220,000(A/P,10%,3)
= 220,000(0.40211)
= $88,464
2.8 P = 75,000(P/F,12%,4)
= 75,000(0.6355)
= $47,663
