Locust is evaluating a switch from a cash only policy to a net $30$ policy. The price per unit is $$49,$ and the variable cost per unit is $$20.$ The required monthly return is $2\%.$ The company currently sells $100$ units per month. Under the proposed policy, the company expects to sell $110$ units per month. What is the NPV of granting a new customer in case of a permanent sale, if the probability of customer default is $20\%?$
