52-y+4
(2/3) (52-y+4)+3=25 ;; (1/3) get off, so (2/3) left
(2/3)(52-y+4) =22
52-y+4=33
-y=-23
y=23

1. Take Mike's total from last month and add it up with the service fee. ($1423 + $7.50)
2. 1430.5 is your total, then multiply that by .5% for intrest fee. Intrest fee is $7.153
3. You take $1430.5 + $7.153
TOTAL. $1437.65
Hope this helped.
