Consider a project with a $4-$year life and no salvage value. The initial cost to set up the project is $$100,000.$ This amount is to be linearly depreciated to zero over the life of the project.

The price per unit is $$80,$ variable costs are $$64$ per unit and fixed costs are $$10,000$ per year. The project has a required return of $13\%.$ Ignore taxes. $1.$ How many units must be sold for the project to achieve accounting break$-$even? $2.$ How many units must be sold for the project to achieve cash break$-$even? $3.$ How many units must be sold for the project to achieve financial break$-$even? $4.$ What is the degree of operating leverage at the financial break$-$even?
