Answer:
$8700
Explanation:
since there are 12 months in a year:
5600 x 12 = $67200
pay per week: 25 x 45 = $1125
pay per year: 1125 x 52 = $58500
67200 - 58500 = $8700 left over
not too sure by what you meant with the question (How does this rate cover your expenses?) but i hoped this helped in some way :)
