Problema Solution
A store mixes Kenyan coffee worth $11 per Kilogram and Turkish coffee worth $14 per kilogram. The mixture is to sell for $12 per kilogram. Find how much of each should be used to make a 408-Kilogram mixture.
Answer provided by our tutors
let
x = is the weight of Kenyan coffee
y = is the weight of Turkish coffee
11*x + 14*y = 12*(x + y)
x + y = 408
by solving the system of equations we find that
x = 272 kg
y = 136 kg
The store should use 272 kg Kenyan coffee and 136 kg Turkish coffee to make the mix.
