1. A new production system for a factory is to be purchased and installed for $114,666. This system will save approximately 300,000 kWh of electric power each year for a 6-year period. Assume the cost of electricity is $0.10 per kWh, and factory MARR is 15% per year, and the salvage value of the system will be $8,666 at year 6. Using the AW method to analyzes if this investment is economically justified

A. calculate the AW of the above investment and insert the result below.

B. Based on the AW value you got in the previous question, is this investment economically justified or not? type you explanation below

2. A. For the below ME alternatives , which machine should be selected based on the AW analysis. MARR=10%
