Question 574983
a store mixes Kenyan coffee worth $11 per kilogram and Turkish coffee worth $15 per kilogram.
 The mixture is to sell for $14 per kilogram.
 Find how much of each should be used to make a 276 kilogram mixture.
:
Let x = amt of $15 coffee
the total is to be 267 kg, therefore
(276-x) = amt of $11 coffee
:
A typical mixture equation:
:
15x + 11(276-x) = 14(276)
15x + 3036 - 11x = 3864
15x - 11x = 3864 - 3036
4x = 828
x = {{{828/4}}}
x = 207 kg of $15 coffee:
:
You can find how much $11 coffee
