Question 1055797
A store mixes Brazilian coffee worth $11 per kilogram and Turkish coffee worth 
$14 per kilogram. The mixture is to sell for $13 per kilogram. 
Find how much of each should be used to make a 528​-kilogram mixture. 
How many kilograms of the Brazilian coffee should be in the ​mixture? 
---------------------
value + value = value
11x + 14(528-x) = 13*528
------------------------------
11x + 14*528 - 14x = 13*528
----------------------------------
-3x = -528
-----
x = 176 kg (amt of $11 coffee needed)
528-x = 352 kg (amt of $14 coffee needed)
