Abbas earned in a year Ea = $ 17 700
Let's say that :
Ec = Ea + $ 525 = > monthly
Xc = $ 1 250
Ec : Celine ́s earnings (monthly)
Xc : Celine’s expenses (monthly)
Ea : Abbas’ earnings (monthly)
On month # 11 = > Sc = (Ec - Xc)(11) = > $ 8 250 = (Ec - Xc)(11)
Sc : Celine’s savings
$ 8 250 = (Ec - Xc)(11)
$ 8 250 = (Ea + $ 525 - $ 1 250)(11)
$ 750 = Ea - $ 725
Ea = $ 1 475 (monthly)
Ea = $ 17 700 (year).
