A cup of coffee milk is 35% coffee syrup with a second cup of coffee milk that is 65% coffee syrup. How many kilograms of each cup of coffee milk must be combined to get 20 kilograms of coffee milk that is 41% coffee syrup
Answered by Reiny
amount of the 35% stuff --- x kg
amount of the 65% stuff --- 20 - x kg

.35x + .65(20-x) = .41(20)
multiply by 100
35x + 65(20-x) = 820
35x + 1300 - 65x = 820
-30x = -480
x = 16 kg
you state the conclusion
