Answer:
b) 25.0%
Step-by-step explanation:
Calculation to determine what Department 1's contribution to overhead as a percent of sales is
First step is to calculate the Contribution to overhead
Using this formula
Contribution to overhead=Sales - Cost of goods sold - Direct expenses
Let plug in the formula
Contribution to overhead=1,080,000 - $708,000 - 102,000
Contribution to overhead= $270,000
Now let calculate the Contribution to overhead as a percent of sales using this formula
Contribution to overhead as a percent of sales=Contribution to overhead/Sales
Let plug in the formula
Contribution to overhead as a percent of sales=$270,000/$1,080,000
Contribution to overhead as a percent of sales= 25%
Therefore Department 1's contribution to overhead as a percent of sales is 25%
