Question 23 Walsh Corporation is presently making part U98 t
Solution
Step 1:- Calculation of total cost for 7,000 units if produced internally
Particulars Cost per unit
1. Direct materials $3.70
2. Direct labour $3.60
3. Variable overhead $1.40
4. Supervisor\'s salary $4.00
5. Total variable cost $12.70
Total cost for 7,000 units = $88,900.00 (7,000 * $12.70)
Note :
a) Depreciation of special equipment is irrelevant for decision making because it is an historical cost.
b) Allocated general overhead is irrelevant for decision making because it is common cost of the company. So, we are going to incur this cost whether we are producing internally or purchasing from an outsider.
Step 2:- Calculation of total cost for 7,000 units if buying from outsider
Particulars Cost
1. Purchase cost (7,000 * $17.10) $119,700.00
2. Less : Additional margin generated ($24,000.00)
for producing other product
3. Total purchase cost $95,700.00
Step 3:- Calculation of financial advantage(disadvantage) of buying part U98 from the outsider
Particulars. Amount
1. Total cost if produced internally. $88,900.00
2. Total cost if purchased from outsider. $95,700.00
3. Advantage/(disadvantage) (1-2) ($6,800.00)
By comparing the above two costs the total disadvantage of buying a part from outsider is ($6,800.00)
So option to this question is \"b\"
