*NOTE the goal is to solve problem 2!

The operating and maintenance costs of a machine are $5,000 the first year and are expected to increase by $700 for the remaining 9 years. What is the uniform annual uniform cost if the interest rate is assumed to be 10 % ? In the above problem, if the annual cost is expected to decrease by $700 for the remaining 9 years, what is the present worth of the costs? Draw the cash flow diagram
