Evaluating Credit Policy Solar Engines manufactures solar engines for tractor$-$trailers.

Given the fuel savings available, new orders for $125$ units have been made by customers

requesting credit. The variable cost is $$14,800$ per unit, and the credit price is $$16,100$

each. Credit is extended for one period. The required return is $1\mathrm{.}9$ percent per period. If

Solar Engines extends credit, it expects that $30$ 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. Should credit be extended?
