The first audit of the books of Halpert Company was made for the year ended December 31, 2021. In examining the books, the auditor found that certain items had been overlooked or incorrectly handled in the last 3 years. These items are:

1. At the beginning of 2019, the company purchased a machine for $120,000 (salvage value of $20,000) that had a useful life of 10 years. The bookkeeper used straight-line depreciation but failed to deduct the salvage value in computing the depreciation base for the 3 years.

2. At the end of 2020, the company failed to accrue sales salaries of $35,000.

3. In 2021, the company wrote off $90,000 of inventory considered to be obsolete; this loss was charged directly to Retained Earnings.

Instructions Prepare the journal entries necessary in 2021 to correct the books, assuming that the books have not been closed. Disregard effects of corrections on income tax.
