Answer:
The range of demand that will be best for each option is that INSOURCING will be optimal between 1 and 37,500 units while OUTSOURCING on the other hand will optimal for annual demand of ≥37,500 units
Explanation:
Calculation for Over what ranges of demand is each option best
Using this formula
Range of demand = (Annual Fixed Cost-Annual cost ) / [Unit cost per subassembly-(Materials costs per unit +Labor costs per unit)
Let plug in the formula
Range of demand = ($250,000 - $400,000)/[$8 - ($7+$5)]
Range of demand = ($250,000 - $400,000)/($8-$12)
Range of demand =$150,000/$4
Range of demand = 37,500
Based on the above calculation the range of demand that will be best for each option is that INSOURCING will be optimal between 1 and 37,500 units while OUTSOURCING on the other hand will optimal for annual demand of ≥37,500 units
