Three different liquids are mixed together in order to create new drinks. The liquid types (A,B,C) have different amount of sugar(S) and coffeine(C).
S% C%
Liquid A 6% 23%
Liquid B 10% 38%
Liguid C 4% 11%
The production goal is 2000L. Is it possible to mix the liquids so that mix contains
a)8% of sugar and 30% of coffeine
b)5% of sugar and 21% of coffeine
How much of each liquid would need to be mixed in to get the desired results?
How would you solve this, and what kind of equations would you use?
I am completely lost with this problem and I am quitenew to MathCad.
