The answer to that problem is 27. You could divide 108 by 4 and get the answer of 27
Ok, to solve this first you have to set up your proportion:
9/150=x/230
/ is a fraction
x= the number of vials it will take to treat 230 patients
in order to solve this, you have to cross multiply:
9 x 230= 2070
150 · x= 150x
so you get 150x=2070
then divide 2070 by 150
2070/150= 13.8
so it would take 13.8 vials of medicine to treat 230 patients
387
Hope this helped!!!!!
y-intercept for x = 0.
Substitute x = 0 to the equation of the function:

I think the answer is 8.5 h
