A coffee distributor needs to mix a(n) House coffee blend that normally sells for $8.40 per pound with a Mexican Shade Grown coffee blend that normally sells for $14.70 per pound to create 70 pounds of a coffee that can sell for $14.61 per pound. How many pounds of each kind of coffee should they mix?

Answer 1

add up the value of the parts:

8.40x + 14.70(70-x) = 14.61*70

Expect a value of nearly zero for x, since the price of the mix is very close to the price of the Mexican coffee.
