 Question 102426: I looked over my notes several times, but I still have trouble setting up the problem and solving it. I'm not even sure I have this under the right category. This is being solved using a Quantity-Value Table. Juan has coffee that sells for \$9 a pound and \$4 a pound. How many pounds of each must be mixed to get 20 pounds of coffee worth \$8.25 a pound? I know the table is set up as Q|V|Q*V. What I tried using was x*4, x*9, and 20*8.25. I'm not sure I have it set up correctly. Then I got to 9x+4x=165. Solve and get x = 165/13. I know I'm supposed to apply that answer to get the resulting answer for both the \$9 a pound and \$4 a pound, but I'm not sure how. Please and thank you for any help you can give!
