Answer:
The journal entries should be as follows:
July 1, purchase of 3-year insurance policy
Dr Prepaid insurance 13,500
Cr Cash 13,500
December 1, paid for two years of advertising in local radio
Dr Prepaid advertising 36,000
Cr Cash 36,000
By December 31, the adjusting journal entries should be:

Cr Prepaid insurance 2,250
*insurance expense = ($13,500 / 36 months) x 6 months = $2,250
Dr Advertising expense 1,500
Cr Prepaid advertising 1,500
*advertising expense = ($36,000 / 24 months) x 1 month = $1,500
