What I want to know is how to set up an algebraic equation that will show me how many days I will be taking this medication for until it is gone.. Now Ive already figured it out in a childish 6th grader manner and I know that the answer is 43 days. This is how I did it:
9600mg Total
120mg/day/week, 840mg, week 1
160mg/day/week, 1120mg, week 2
200mg/day/week, 1400mg, week 3
240mg/day/week, 1680mg, week 4
280mg/day/week, 1960mg, week 5
320mg/day/week, 2240mg, week 6
Finally. 360mg for 1 day = 9600mg total.
6 weeks and 1 day. 43 days.
I had to figure out for each weak individually but I KNOW there is has to be some kind of equation for this I just have NO idea how to set it up with the sum of how many mg's I have to take changing every week. So if anyone can figure it out that would be awesome.
