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. > How would I solve this using math instead of geustimating it. > What kind of math am I talking about here? 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.
