Please solve this problem,

An analysis of the accounts shows the following. Insurance expires at the rate of $320 per month. Supplies on hand total $960. The equipment depreciates $200 per month. During March, services were performed for two-fifths of the unearned service revenue. Prepare the adjusting entries for the month of March. (If no entry is required, select "No Entry" for the account titles and enter O for the amounts. Credit account titles are automatically indent when the amount is entered. Do not indent manually.)
