Explanation / Answer
Question-1)
Solution:
(a) Per door knob cost of manufacturing is calculated as;
Per door knob cost of manufacturing = Total cost of manufacturing / Batch size
Per door knob cost of manufacturing = ($5000 + $4000 + $2000) / 1200
Per door knob cost of manufacturing = $11000 / 1200
Per door knob cost of manufacturing = $9.17
(b) Since, the cost of manufacturing the door knobs is $9.17 per knob while the cost of buying it from a specialized manufacturer is $10 per knob, the decorative doors should make the door knobs.
Answer: Option (A) - Make
Question-2)
Solution:
(a) The total cost of manufacturing a batch of buttons (Batch size = 1500) is calculated as;
Total cost = Direct Materials + Direct Labour + Factory Overhead
Total cost = $900 + $750 + $400
Total cost = $2,050
The total cost of manufacturing a batch of buttons = $2,050
(b) Per button cost when manufactured is calculated as;
Per button cost = Total cost of manufacturing / Batch size
Per button cost = $2050 / 1500
Per button cost when manufactured = $1.37 per button
Per button cost when purchased from other manufacturer = $1.75 per button
When the company buy their buttons from other manufacturer, they have to pay additional cost per button of $0.38 ($1.75 - $1.37). That is, $570 for a batch size of 1500 buttons. However, they could use their plant for other manufacturing and increase their profit by $3,000.
Net profit = $3000 - $570
Net profit = $2430
Therefore, Casual wear should buy buttons and increase production.
Answer: Option (C) - buy buttons and increase production
Question-3)
Solution:
(a) Original production cost = $5000
Updating cost = $2000
Selling price = $7500
The net result of reworking the MP3 players is calculated as;
Profit = Total Revenue - Total Costs
Profit = ($7500) - ($5000 + $2000)
Profit = $500
The net result of reworking the MP3 players is a profit of $500
(b) Reworking the MP3 players will result in a profit of $500 for Songo, while scrapping the MP3 players will result in a loss of $1500 ($5000 - $3500).
Therefore, Songo should rework the outdated MP3 players.
Answer: Option (A) - Rework
