Final answer:
The NPV of granting credit to a new customer when taking into account the variable cost, selling price, probability of default, and monthly required return is $40.78.
Step-by-step explanation:
To calculate the net present value (NPV) of granting credit to a new customer, we need to evaluate the cash flows considering the variable cost, selling price, probability of default, and the required return. We use the formula:
NPV = Selling Price - Variable Cost - (Probability of Default × Selling Price) / (1 + Monthly Required Return)
First, we calculate the expected revenue after accounting for the probability of default:
Expected Revenue = Selling Price × (1 - Probability of Default)
Expected Revenue = $120 × (1 - 0.22) = $93.60
Then we adjust this for the cost and required return to get NPV:
NPV = ($93.60 - $52) / (1 + 0.02)
NPV = $41.60 / 1.02
NPV = $40.78
Therefore, the NPV of the switch is $40.78, rounded to two decimals.
