Answer:
$2,000
Explanation:
The amount which is to be recorded for the service revenue for the month of the December 2018 is computed as:
Service revenue = Monthly Salary / Number of days in the month of December Ă— Number of days from being hired
where
Monthly salary is $4,000
Number of days in the month of December is 30 days
Number of days from being hired is 15 days (From 15 December to 30 December)
Service revenue = $4,000 / 30 days Ă— 15 days
Service revenue = $133.33 Ă— 15 days
Service revenue = $1999.95 or $2,000
Therefore, the service revenue for the month of December amounts to $2,000.
