Final answer:
The correct entry to record the progress billing in a Capital Projects Fund is option c, which credits Construction contracts payable for $18 million, reflecting the 90% payment after the city retains 10% of the total billed amount.
Step-by-step explanation:
The correct option to record the progress billing in a Capital Projects Fund when a contractor sends a progress billing report to a city requesting payment of $20 million for work done to date on a new fire station, and the city retains 10 percent of the payment, is option c. Construction contracts payable is credited for $18 million.
The contractor has billed the city for $20 million, but due to the retainage clause (10% holdback until completion and inspection), the city will only pay 90% of the amount billed at this time. Therefore, the construction contracts payable would reflect the actual amount the city is liable to pay at this moment, which is $18 million (90% of the $20 million billed).
The retainage amount of 10%, which amounts to $2 million ($20 million x 10%), will be recognized in a separate liability account titled Retainage Payable.
