Engineering Economy ENGR 300 Chapter 3 3-2 Under most circumstances \$20,000 received now would be more valuable. The present worth factors for n = 4, i.e. (P/A, i, 4), are all less than 4 for interest rates greater than 0. Receiving \$5,000 per year for four years would only potentially be more valuable for certain conditions of deflation and/or transitioning into a lower incremental tax bracket. 3-3 Under most circumstances \$20,000 received now would be more valuable.

Receiving \$5,000 per year for four years would only potentially be more valuable for certain conditions of deflation and/or transitioning into a lower incremental tax bracket. 3-8 P = \$750, n = 3 years, i = 8%, F = ? F = P (1 + i) n = \$750 (1.08)3 = \$750 (1.260)= \$945 Using interest tables: F = \$750 (F/P, 8%, 3) = \$750 (1.360) = \$945 3-11 Use P = F (P/F, i, n) = F (1 + i)-n = 20,000 (1 + 0.07)-n.
