6. Wexby Designs currently has a cash only policy, but is considering going to a net 30 days policy. Its sale price per unit is $125 and its variable cost per unit is $96. It currently sells 1,320 units per month, and believes that under the new policy it will sell 1,350 units per month. The required return is 0.95% per month. What is the net present value of this proposed change? Should the company make it?
