Error analysis and correcting entry

Assume that you have been engaged to review the financial statements of a company. In the course of your examination, you conclude that the bookkeeper hired during the current year is not doing a good job. You notice a number of irregularities, as follows:

1. Year end salaries and wages payable of $3,400 were not recorded because the bookkeeper thought that they were immaterial.

2. Accrued vacation pay for the year of $31,100 was not recorded because the bookkeeper never heard that he had to do it.

3. Insurance for a 12-month period purchased on November 1 of this year was charged to insurance expense in the amount of $3,300 because according to the bookkeeper, the amount of the check is about the same every year

4. Reported sales revenue for the year is $1,980,000. This includes all sales taxed collected for the year. The sales tax rate is 10%. Because the sales tax is forwarded to the Department of Revenue, the Sales Tax Expense account is debited. The bookkeeper thought that the sales tax is a selling expense. At the end of the current year, the balance in the Sales tax expense account is $103,400

Instructions:

Prepare the necessary correcting entries, assuming that the company uses a calendar-year basis
