Still confused with this and how the other tutor got 3.20 for part of the equation

Neal Manufacturing Inc. has been approached by a customer who wants to place a one-time order for a component similar to one that they make for another customer. Existing sales will not be affected by acceptance of this order. The manufacturing costs and the targeted selling price for the component currently being made are below. The direct materials used in the new component for the new customer would cost $.50 more than those in the component currently being made. The variable selling expenses would be $1.25 per unit. What is the minimum unit price at which Neal Manufacturing would be willing to accept the special order? Please complete and upload your work in an excel spreadsheet. Show all work.
