An Iron Casting Company Has Received an Order to Supply

An iron casting company has received an order to supply 300 units of casted fireplace inserts each year for
Midwestern Builders over a 2-year period. The current sales price is $1,500 per unit, and the current cost per
unit is $1,000. The firm is taxed at a rate of 30%. Both prices and costs are expected to rise at a rate of 6% per
year. The firm will produce these units on fully-depreciated existing machines. Since the orders will be filled at
the end of each year, the unit sale price and unit cost during the first year would be $1,590 and $1,060,
respectively. The firm's market interest rate is 15%. Compute the net present worth of this project.
