Answer:
A. Make carrying case(Alternative 1) $41.00
Buy carrying case (Alternative 2)$44.00
Differential effect on net income (Alternative 2)($3.00)
B. Assuming there were no better alternative uses for the spare capacity, it would BE ADVISABLE to manufacture the CARRYING CASES. Fixed overhead is IRRELEVANT to this decision.
Explanation:
A. Preparation of a Differential Analysis
DIFFERENTIAL ANALYSIS
Make carrying case Buy carrying case
(Alternative 1) (Alternative 2)
Alternative 1 Alternative 2 Differential effect on net income (Alternative 2)
Sales price
$0.00 $0.00 $0.00
Purchase Price
$0.00 $40.00 ($40.00)
Direct materials
$16.00 $0.00 $16.00
Direct labor
$20.00 $0.00 $20.00
Variable manufacture overhead (20*5%=$1.00)
$1.00 $0.00 $1.00
Fixed manufacture overhead($5.00-$1.00) $4.00 $4.00 $0.00
Income(Loss)
$41.00 $44.00 ($3.00)
Based on the above calculation Alternative 1 which is carrying case should be Choose by the Company .
B. Therefore Assuming there were no better alternative uses for the spare capacity, it would BE ADVISABLE to manufacture the CARRYING CASES. Fixed overhead is IRRELEVANT to this decision.
