Answer: $45
Step-by-step explanation:
As for the information provided,
The weekly rate of wages = $615
In a year there are 52 weeks, thus annual wages = $615 52 = $31,980
But since one week is an unpaid leaves, there will be no wages for such week.
Accordingly, annual wages shall be reduced by wages of a week = $31,980 - $615 = $31,365
Note: When the leaves are paid leaves wages are earned for such period.
Also the annual expected expenses = $31,320
Therefore, expected surplus at year end = $31,365 - $31,320 = $45
