Answer:
Accounts receivable balance as at March 31 = $ 16,000
Explanation:
The adjusting entry for the earned revenue on the contract is calculated as follows:
Total contract Value $ 30,000
Period of contract 6 months
Earned Revenue per month $ 5,000
Period of earning 2 months
Earning for the period February 1 to March 31 2 * $ 5,000 = $ 10,000
The accounting entry would be
Accounts Receivable $ 10,000
Revenue $ 10,000
so the receivable balance after adding $ 6,000 is $ 16,000
