A large construction job will take 4 years to complete. The costs of the many required inspections can be reduced by purchasing a voice recognition system to act as the "front end" for a word processor. Then, inspectors can be trained to record their comments and revise the written output of an automated form. The firm's interest rate is 12%. The first cost for purchase and training is $100K. Savings are estimated at $30K, $40K, $65K, and $35K for the 4 years of construction. Draw the project balance and determine the initial cost, the discounted payback period, and the future worth. $65K $40K $30K $35K $100K
