OK, No fancy math here, so thee might be a cleaner way, but here
is how I'd do it.
> (Note the patient only has 5mg tabs, which they can split to make
dose
> adjust my 2.5)
OK< so we are dealing with a unit size of 2.5mg. Convert the total
dosage into 2.5mg units. 35mg = 35/2.5 = 14 units
Divide the number of units by the number of days using integer
division:
divmod(14,7) -> 2,0
that tells us you need 2 units per day and no adjustment
Add 10% => 14 + 1.4 = 15.4 units. YOu must decide to either
round up or down, lets say you round up to 16 units
divide the doze as before
divmod(16,7) -> 2,2
that says 2 units per day and on 2 days an extra unit.
(Which was your guestimate)
If you rounded down to 15
divmoid(15,7) -> 2,1
which is 2 units/day and 1 day with an extra unit.

integer math with a hint of quantum techniques thrown in
If the above didn't make sense just shout and we can explain
in more detail.
