Final answer:
The minimum transfer price for the Mechanical Division is RM 30, which covers the variable production costs. The maximum the Engineering Division would theoretically pay is RM 57, making an internal transfer price of RM 58 unattractive. An internal transfer at RM 36 would not be beneficial for the Mechanical Division as it's below their variable production costs.
Step-by-step explanation:
Minimum Transfer Price Calculation
The minimum transfer price for the Mechanical Division would be the sum of the direct materials, direct labor, and variable overheads, which amounts to RM 20 + RM 4 + RM 6 = RM 30 per unit. This price covers the variable costs associated with producing one more unit for the Engineering Division, and therefore, it is the lowest price that the Mechanical Division would accept for an internal transfer.
Maximum Transfer Price Calculation
The maximum transfer price that the manager of the Engineering Division would pay is the current external purchase price, which is RM 56 per unit. Because the variable selling expenses of RM 1 per unit are avoidable if the part is sold internally, theoretically, the Engineering Division could pay up to RM 57 (RM 56 + RM 1 saved). However, at RM 58, the Engineering Division manager would likely decline as it would be more expensive than their current external purchase price.
Internal Transfer Decision
An internal transfer should be considered beneficial if it leads to overall cost savings for the company and doesn't negatively impact the profitability of the selling division. If the Mechanical Division sells at RM 36, which is below the variable cost per unit, it would not cover the full costs of production, leading to a loss on each unit sold internally. Therefore, selling at RM 36 each would not be favorable for the Mechanical Division.
Income Statement and ROI Calculation
To prepare an income statement for the Mechanical Division and calculate its operating income with the transfer price of RM 42, we need to consider total revenues (RM 42 * 50,000), total variable costs, and fixed costs. The ROI would be calculated by taking the operating income and dividing it by the average operating assets. Without complete financial data, we cannot perform these calculations in full.
