Answer: Higher by $15,540.
Explanation:
Insurance was paid for a year on October 1 therefore it lasted only 3 months in the year. That needs to be reflected.
= 14,000 * 3/12
= $3,500
$3,500 in insurance for the year.
Advanced $12,000 for principal and note due in a year on June 30 leaving only 6 months in the year. Accounting for that will be,
= 12,000 * 6% * 6/12
= $360
Equipment cost was not an adjusting error but the depreciation is. Depreciation for the year is $12,400.
Adding all the adjusting entries,
= 3,500 + 360 + 12,400
= $15,540
All of the above were expenses to be taken out of Net Income. Therefore if they were not recorded, Income would be higher by $15,540.
