Answer provided by our tutors
Let
k = kg of the Kenyan coffee
v = kg of the Venezuelan coffee
The mixture is 600 kg
k + v = 600
The mixture is to sell for $12 per kilogram
12k + 16v = 15*600
We have the following system of equations:
k + v = 600
12k + 16v = 15*600

........
k = 150 kg
v = 450 kg
150 kg of Kenyan coffee and 450 kg of Venezuelan coffee should be used to make the 600 kg mixture.
