not sure

anonymous · Answer

we have to introduce a variable.  lets call the number of kilos of turkish coffee $x$ so then the number of kilos of kenyan must be $228-x$ becauseteh total is 228

anonymous · Answer

if you have $x$ kilos of turkish, then it cose $14\times x$ and the $228-x$ kilos of kenyan cost 
$11\times (228-x)$

anonymous · Answer

all together you want the total cost to be $12\times 228=2736$ so set 
$$14x+11(228-x)=2736$$ and solve for $x$
