Very difficult problem with mixtures
Posted:

Hi,
Can anyone help me with this problem?
Toothpaste in the Basement
Elana mixes the tootpastes in large tanks in her basement after school. Both flavors are made from only four ingredients, which well call A, B, C, and D to preserve Elanas trade secrets. Ingredients A, B, and D are pumped into Tank 1 and mixed to make Candy Madness, which requires 2 gallons of B and 3 gallons of D for every gallon of A. Twothirds of this mixture are drained and packaged, but onethird is pumped into Tank 2 where it is mixed with other ingredients to make Maple Sugar Supreme. This second recipe requires three times the amount of A used in Candy Madness, and it is flavored with 2 gallons of C for every 3 gallons of A.
If Elanas process produces 21 gallons of Maple Sugar Supreme per hour, how many gallons of Candy Madness are produced per hour?
