You can put this solution on YOUR website! a pharmacist wants to mix a medicine that is 10% aspirin with a medicine that is 25% asprin to make 10 grams of a medicine that is 16% asprin. how many grams of each medicint should the pharmacist mix together?
-----
Equation:
aspirin + aspirin = aspirin
0.10x + 0.25(10-x) = 0.16*10
----
Multiply thru by 100 to get:
10x + 25*10 - 25x = 16*10
------
-15x = -9*10
x = (2/3)9
---
x = 6 grams (amt. of 10% medicine needed)
----
10-x = 4 grams (amt. of 25% medicine needed)
