Answer:
$45
Step-by-step explanation:
A surplus is when income exceeds expenses.
One year has 52 weeks. If one week was unpaid leave, then payments were received for 51 weeks.
Average payments per week = $615
Total earning per week =$615 x 51
=$31,365
The total expenses for the year were $31,320. The surplus amount will be income minus expenses
= $31,365 - $31,320
=$45
