Answer:
$2,000
Step-by-step 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 × 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 × 15 days
Service revenue = $133.33 × 15 days
Service revenue = $1999.95 or $2,000
Therefore, the service revenue for the month of December amounts to $2,000.
