Now, the ABC Company has identified another potential supplier for the molded plastic parts. The new supplier has bid $0.1500 per part but also will impose a shipping and handling charge of $0.0050 per unit. Additional inventory handling charges should amount to $0.0050 per unit. Finally, purchasing costs are estimated at $20 per month for the length of the 36-month contract. Note that the forecasted demand is a total of 1 million units over the 36 months.

The outsourcing option with the new supplier is cheaper than insourcing b. Suppose the three-year volume is expected to rise to 1.5 million, rather than 1 million, molded plastic parts. The total cost per unit associated with insourcing is now $ 0.2503. (Enter your responses rounded to four decimal places.) What explains the difference? O A. The difference in cost per unit is explained only by the larger volume absorbing the fixed engineering/design costs. B. The difference in cost per unit is explained only by the larger volume absorbing the fixed "equipment depreciation." C. The difference in cost per unit is explained by the larger volume absorbing the fixed "equipment depreciation" and "engineering design costs." OD. None of the above
