Tennindo, Inc. is starting up its new, cost-efficient gaming system console, the yuu. Tennindo currently has 3,500 cash-paying customers and makes a profit of

$40 per unit. Tennindo wants to expand its customer base by allowing customers to buy on credit. It estimates that credit sales will bring in an additional 1,100

customers per year, but that there will also be a default rate on credit sales of 5%. It costs $250 to make a yuu, which retails for $290. If all customers (old and new) buy on credit, what is the cost of bad debt without credit screening? What is the most Tennindo would pay for credit screening that accurately identifies bad-debt customers prior to the sale? What are the increased profits from adding credit sales for customers with and without credit screening? Should Tennindo offer credit sales if credit screening costs $10 per customer?
