By Michael Coldagelli. Due on Oct. 2nd, 11:59pm A chemist mixes a 12% acid solution with a 20% acid solution to
make 300 milliliters of an 18% acid solution. How many milliliters
of each solution does the chemist use?
a = amount of 12% solution (ml)
b = amount of 20% solution (ml)
Sa+b = 300
100||0.12a +0.20b = 54 12a + 20b = 5400
