The government has established a policy for setting public utility rates for the next 5 years. The defined cost per kWh for the coming year is $0.13. Starting in year 2, CODENSA wants to increase the rate annually by $0.03 per kWh. Assume a discount rate of 8% E.A. You believe that increasing the rate each year is not "politically appropriate." Instead, you prefer to decree a single increase. What should be the rate increase that is equivalent to the CODENSA proposal?
