Answer:
c. $2,377,778
Step-by-step explanation:
Recording the entire cost as expense would have understated Retained Earnings by $3,000,000
Annual Depreciation on machine = Purchase cost - Residual value / Useful life
= ($3,000,000 - $200,000) / 9
= $311,111
Depreciation would have been recorded for $622222 for 2 years had machinery been correctly recorded ($311,111 * 2) = $622,222
On December 20, 2018, the net understatement of Retained Earnings = $3,000,000 - $622,222
= $2,377,778
