Solar Engines manufactures solar engines for tractor$-$trailers. Given the fuel savings available, new orders for $115$ units have been made by customers requesting credit. The variable cost is $$8,800$ per unit, and the credit price is $$10,750$ each. Credit is extended for one period. The required return is $1\mathrm{.}4$ percent per period. If Solar Engines extends credit, it expects that $35$ 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 i
