Answer:
A Region
Allocation of service department expense is $42,840
Operating Income is $107,160
B Region
Allocation of service department expense is $77,160
Operating Income is $247,840
Explanation:
A Region
Percentage of sales allocation = Sales / Total of sales of both region
= $500,000 / ($500,000 + $900,000)
= $500,000 / $1,400,000
= 35.7%
Allocation of service department expense:
= Percentage of sales allocation × (Purchasing + Payroll accounting)
= 35.7% × ($90,000 + $30,000)
= 35.7% × $120,000
= $42,840
The computation of Operating Income is as:
Operating Income = Sales - COGS - Selling expense - Allocation of service department expense
= $500,000 – $200,000 – $150,000 – $42,840
= $107,160
B Region
Percentage of sales allocation = Sales / Total of sales of both region
= $900,000 / ($500,000 + $900,000)
= $900,000 / $1,400,000
= 64.3%
Allocation of service department expense:
= Percentage of sales allocation × (Purchasing + Payroll accounting)
= 64.3% × ($90,000 + $30,000)
= 64.3% × $120,000
= $77,160
The computation of Operating Income is as:
Operating Income = Sales - COGS - Selling expense - Allocation of service department expense
= $900,000 – $300,000 – $275,000 – $77,160
= $247,840
