Suppose you work for a large coffee distributor that has a secret coffee blend it sells to local stores. You mix the Terraza blend with the Kona blend, but always in the same proportion. Yesterday, you mixed 80 pounds of the Terraza blend with 24 pounds of the Kona blend. Today, there is 70 pounds of the Terraza coffee left in stock. How many pounds of the Kona coffee should you mix with it to get your secret blend?
