Answer:
See below
Step-by-step explanation:
Recording the entire cost as expense would have understated retained earnings by $2,650,000
Annual depreciation on machine = ( Purchase cost - Residual value ) / Useful life
= ($2,650,000 - $165,000) / 9
= $2,485,000 / 9
= $276,111.11
Depreciation would have been recorded for $552,222 for 2 years had the machinery been corrected recorded I.e $276,111 × 2 = $552,222
Therefore , the cumulative effect of this error on the income statement of Sheridan for the year ended, 31 December 2021 would have shown
= $2,650,000 - $552,222
= $2,097,779
