Solar Engines manufactures solar engines for tractor$-$trailers. Given the fuel savings available, new orders for $110$ units have been made by customers requesting credit. The variable cost is $$8,600$ per unit and the credit price is $$10,500$ each. Credit is extended for one period. The required return is $1\mathrm{.}3$ percent per period and the probability of default is $10$ percent. Assume the number of repeat customers is affected by the defaults. In other words, $40$ percent of the customers who do not default are expected to be repeat customers. Calculate the NPV of the decision to grant credit. $($Do not round intermediate calculations and round your answer to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$
