A project has projected annual sales of 30,000 units with a selling price of $6.00 each. Annual fixed costs are $40,000 with variable costs of $3.60 per unit. The project has a three-year life and requires an initial investment of $75,000 for equipment. The equipment will be depreciated straight-line to zero over three years. (half-year rule does not apply). The sales price has a plus-minus range of 20% while the variable cost estimate is expected to vary within an 8% range. The sales quantity has a plus-minus range of 10%. The tax rate is 35%. Under the worse-case scenario, what is the annual operating cash flow?
