Answer: $4400
Explanation:
The proper amount of expenses to be included in the income statement for the year will be calculated as:
Commissions for salespeople who made sales in December = $3000
Add: Phone bill = $400
Add: Advertisement = $1000
Total expense = $3000 + $400 + $1000 = $4400
N.B: The commission and telephone charge were incurred in December 2019 and should be added.
The store rent of $2,000 for January 2020 was paid on December 28, 2019. This won't be added since it was for 2020.
Advertisiment of $1,500 was paid for November 2019, December 2019 and January 2020. We are concerned with that of November and December 2019. This will be: $1500 × 2/3 = $1000
