Answer:
425 milliliters of compound A are needed
Step-by-step explanation:
We were told that 
milliliters of compound A and 
milliliters of compound B is needed to make the drug.
This means that each drug contains 11 milliliters of both compounds.
milliliters is the volume of each drug.
Therefore the chemist needed 
millilirteres of compound A.
B and F because they would be multiplied by 100, which would move the digits two times to the right.
S + l. = 34
11s + 21l= 514
-11s - 11l= -374
11s + 21l = 514
10l = 140
l = 20 long sleeve shirts
s + 20 = 34
s = 14 short sleet shirts
-3 + 7 = 4
4 - 7 = -3
I think that's what you want.
