Problema Solution

A coffee distributor needs to mix a(n) Arabian Mocha coffee blend that normally sells for $8.40 per pound with a Ethiopian coffee blend that normally sells for $14.60 per pound to create 60 pounds of a coffee that can sell for $10.78 per pound. How many pounds of each kind of coffee should they mix?

Answer provided by our tutors

Let

x = pounds of the Arabian Mocha coffee blend

y = pounds of the Ethiopian coffee blend

The new mix is 60 pounds:

x + y = 60

And sells for $10.78 per pound:

8.40x + 14.60y = 10.78*60

We have the following system of equations:

x + y = 60

8.40x + 14.60y = 10.78*60
