Beta Corp. wants to decide if it is reasonable to accept checks for the sale of a refrigerator whose production cost is $ 1000. The sale price of that refrigerator is $ 1400. Customer wants to write a check and pay the sale price of the refrigerator after six months. The firm estimates that the probability of payment by the customer on time is 0.80 but there is a 20% probability that the customer may not pay. Assuming that annual interest rate in that country is 20% annually; should the firm accept the check of the customer if the FIFO score of that customer is 820 out of 1 000 ?
