HURRY A $9-$year project is expected to generate annual sales of $10,300$ units at a price of $$90$ per unit and a variable cost of $$61$ per unit. The equipment necessary for the project will cost $$429,000$ and will be depreciated on a straight$-$line basis over the life of the project. Fixed costs are $$260,000$ per year and the tax rate is $24$ percent. How sensitive is the operating cash flow to a $$1$ change in the per unit sales price?
