Final answer:
The year-end adjusting entry to recognize supplies expense for Delta Company involves decreasing Supplies and Retained Earnings by $1,900, which is based on the supplies used during the year.
Step-by-step explanation:
The student asked about the year-end adjusting entry required to recognize supplies expense for Delta Company. The company started with a $700 balance in its Supplies account and paid $1,600 cash for additional supplies. By the end of Year 2, a physical count revealed $400 of supplies on hand. The correct year-end adjusting entry will decrease the Supplies account by the amount of supplies used during the year ($1,900, calculated as the starting balance plus purchases minus the ending balance: $700 + $1,600 - $400) and will also decrease the Retained Earnings to reflect the supplies expense.
The correct adjustment affects the accounting equation as follows:
Assets = Liabilities + Stockholders' Equity
Supplies = Retained Earnings (1,900) (1,900)
