Answer: $20,000
Explanation: This question deals with Compensated Absence.
A compensated absence refers to paid holidays and other paid time off. According to accounting principles, expenses are recognized in the same period they are incurred. When it comes to compensated absences that are deferred to a later year (or period), the amount must be recorded as a liability in the year they are incurred.
Because of this, $40,000 (an average of $800 per week for a total of 500 vacation weeks) will be charged to 2021 expense as a liability.
The amount of salaries expense related to 2022 compensated absence is the average 5% pay rise in 2022.
The amount is therefore 5% X $800 X 500 weeks = $20,000
