Requirement (a)
The cost benefit analysis will be suitable here for short term decision making.
Cost Benefit Net
Increase in Fixed Cost (W-1) ($5000) ($5000)
Increase in Total Contribution (W-2) <u> </u> <u>$2700 </u> <u> $2700 </u>
Net Decrease in Operating Income ($5000) $2700 ($2300)
Working 1 The net increase in the fixed cost is $5000 which is given in the requirement (a).
Working 2 Net increase in Total contribution by increasing the monthly advertising expense by $5000 is:
30% * $9000 = $2700
Requirement (b)
As the net difference is a decrease in operating income by $2300 so it is not a suitable option for the company.
Requirement 2
Again here we will appraise the suitability of the option by using cost benefit analysis.
Cost Benefit Net
Increase in T.Variable Cost (W-3) ($4400) ($4400)
Increase in Total Contribution (W-4) <u> </u> <u>$1000 </u> <u> $1000 </u>
Net Decrease in Operating Income ($4400) $1000 <u>($3400)</u>
Decision: As the net difference is $3400 negative so it is better that we don't opt to increase the component cost by $2.
Working 3 The net increase in the Total Variable cost is:
Increase in Total Variable cost = $2 net increase in variable cost per unit * total units after opting to higher quality components
Increase in Total Variable cost = $2 * (2000*110%) = $4400
Working 4 Net decrease in contribution per unit is $2 as a result of increasing the Variable cost per unit by $2.
Due to the increase in the total number of units sold the total contribution will increase if the difference of contribution on increased units and contribution on older number of units is positive.
Total Contribution after taking the decision to increase variable cost by $2 is:
Total contribution = 2000 * 110% * $(27-2) = $55000
Total Contribution before taking the decision to increase variable cost by $2 is:
Total contribution = 2000 * $27 = $54000
So the Net difference is $1000 positive (55000-54000).
