Solar Engines manufactures solar engines for tractor-trailers. Given the fuel savings available, new orders for 170 units have been made by customers requesting credit. The variable cost is $11,000 per unit, and the credit price is $13,500 each. Credit is extended for one period. The required return is 1.6 percent per period. If Solar Engines extends credit, it expects that 15 percent of the customers will be repeat customers and place the same order every period forever and the remaining customers will be one-time orders. Calculate the NPV of the decision to grant credit. (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
