Question

How much cream that is 20% butterfat should be mixed with milk that is 15% butterfat to get 10 gallons of cream that is 14% butterfat?

Answer 1

This is an algebra problem.
Let's let the variable x stand for the number of gallons of 20% butterfat cream that we add to the mixture.

So we can make an equation that looks like this:
.15(10-x) + .2(x) = .14(10)

If you need more help, let me know.

Answer 2

please solve full

Answer 3

So expanding this gives:
=> 1.5-.15x+.2x=1.4
=> 1.5+.05x = 1.4
=> .05x = -0.1
=> x = -2

...and because we get a negative value for x. I immediately know that this is a silly problem. It is impossible to mix cream and milk which both have a butterfat content greater or equal to 15% and expect them to dilute to 14%. Are you sure you copied the problem correctly?
