Answer with its Explanation:
Requirement A. The cost function is equal to variable cost for "x" units and fixed cost which remains fixed. Hence:
Cost Function = C(x) = $60 + $0.8x
Requirement B. The revenue for any units "x" sold can be calculated by simply multiplying "x" with sales price per unit. Which means that:
Revenue Function = R(x) = $2 * x = $2x
Requirement C. Now we have to find the breakeven quantity and this could be calculated using the following formula:
Breakeven Point = Fixed Cost / (Selling Price per Unit - Variable Cost Per Unit)
By putting values we have:
Breakeven Point = $60 / ($2 - $0.8) = 50 units
Requirement D. As the number of units are above breakeven point (No profit and loss position), hence making sales above 50 units will generate profit for the company.
The profit for the company would be:
Total Profit = Contribution per unit * Units above Breakeven point
Total Profit = ($2 - $0.8) * 10 Units = $12
