Question 1147000: Suppose you work for a large coffee distributor that has a secret coffee blend it sells to local stores. You mix the Tanzanian blend with the Kenya blend, but always in the same proportion. Yesterday, you mixed 90 pounds of the Tanzanian blend with 27 pounds of the Kenya blend. Today, there is 60 pounds of the Tanzanian coffee left in stock. How many pounds of the Kenya coffee should you mix with it to get your secret blend?

Let +x+ = pounds of Kenya coffee to use
+90+%2F+27+=+60+%2F+x+
+90x+=+27%2A60+
+90x+=+1620+
+x+=+18+
18 pounds of Kenya coffee should be used
