Final answer:
The correct adjusting entry for Olive Co.'s prepaid expenses would be a debit to an expense account and a credit to a prepaid expense account for $1,900, which represents the cost of six months' worth of management services.
Step-by-step explanation:
The student is asking about the adjusting entry needed for a prepaid expense recorded by Olive Co. Given that Olive Co. paid $7,600 cash for management services covering a two-year period starting July 1 of the current year, and the question refers to the adjusting entry for December 31 of the same year, we need to account for six months of the service period.
To calculate the expense for six months, we divide $7,600 by 24 months (the total service period) to get the monthly rate, and then multiply by 6 (the number of months from July to December). This results in $1,900 ($7,600 / 24 months = $316.67 per month * 6 months = $1,900).
The appropriate adjusting entry would be a debit to an expense account to recognize the expense incurred and a credit to the prepaid expense account to reduce its balance accordingly. Therefore, the correct journal entry is a debit to an expense and a credit to a prepaid expense for $1,900 (option d). The entry reflects the usage of the service for half a year and the appropriate recognition of the cost of that service as an expense.
