Calculate Present Worth from Project Summary with Uniform Gradient Series.

Revenues are AR the first year, and increase GR each subsequent year

AR = 9.3E3 $

GR = 1.9E3 $

Operation and Maintenance Costs are a Uniform Series of amount AOM

AOM = 4.6E3 $

Capital Costs = 7.1E4 $

Salvage Value = 1.8E4 $

Project Lifetime = 8 yr

Effective Interest Rate = 0.09 (Unitless)

What is the Present Worth of the Alternative?
