Final answer:
The City of Wagner should credit the Option a. 'Due from state government for $15,000' to record the billing to the state for the police officer's salary covered by the grant.
Step-by-step explanation:
The City of Wagner bills the state $15,000 for the police officer's salary in the first quarter of the year as part of the grant received to educate school children on the dangers of illicit drug use. The appropriate accounting entry to record this billing would be to credit an account. Since Wagner must pay out the entire salary and then be reimbursed for half, when they bill the state, they are anticipating a receivable. Therefore, the correct entry would be to credit the Due from state government account.
The full amount of the billing is $15,000, corresponding to the sum Wagner paid for the police officer's salary. As the grant covers half the salary, the expected reimbursement is for this amount, but the credit should reflect the billing amount.
The correct account and amount to be credited by Wagner to record the billing to the state is therefore 'Due from state government for $15,000'.
