Ответ:
Let 8 milliliters of compound A and 5 milliliters of compound B be a mixture.
We can then find how many mixture is needed for 845 milliliters of the drug by dividing it by (8+5=13):
845 ÷ 13
=65
As 65 mixture is used and each mixture include 5 milliliters of compound B, we can find the amount of compound B by multiplying 65 by 5
65 x 5
=325 milliliters
Therefore the answer is 325 milliliters.
Hope it helps!
