Question 570639: shamrock has 900 pounds of milk that is 2% butterfat, how much butterfat do they have to add to raise the butterfat content to 8%? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! percent ---------------- quantity
Milk 2 ---------------- 900 pounds
Butter fat 100 ---------------- x pounds
Mixture 8 ---------------- 900 + x pounds
sum of individual components = quantity in mixture
2*900+100x=8(900+x)
1800+100x=7200 +8x
100x-8x =5400
92x=5400
x= 5400 / 92
x= 58.7
58.7 pounds of Butter fat has to be added
