Final answer:
The operating cash flow (OCF) for the project increases by $9.48 for each additional unit sold, based on the given costs, price, and tax rate.
Step-by-step explanation:
To calculate how sensitive the operating cash flow (OCF) is to changes in quantity sold, we first need to compute the initial OCF using the provided information. We apply the formula OCF = (Sales - Variable Costs - Fixed Costs)(1 - Tax Rate) + (Depreciation * Tax Rate), where Sales = Price * Quantity, and Depreciation is calculated using the straight-line method. Let's compute the initial OCF and then determine the change in OCF due to a change in quantity sold.
Initial Sales = $28 * 61,000 units = $1,708,000
Initial Variable Costs = $16 * 61,000 units = $976,000
Depreciation = Initial Fixed Asset Investment / Project Life = $655,000 / 4 = $163,750 per year
Initial OCF = (($1,708,000 - $976,000 - $245,000) * (1 - 0.21)) + ($163,750 * 0.21) = ($487,000 * 0.79) + $34,388 = $384,630 + $34,388 = $419,018
Now, let's determine how a change in quantity sold by one unit affects OCF. For one additional unit sold: Change in Sales = $28, Change in Variable Costs = $16, Change in OCF = ($28 - $16)(1 - 0.21) = $12 * 0.79 = $9.48 per unit.
Therefore, the OCF is sensitive to the quantity sold by $9.48 for each additional unit sold.
