You can put this solution on YOUR website! Donna wants to make trail mix up of almonds, walnuts, and raisins. She wants to mix one part almonds, two parts walnuts, and three parts raisins. Almonds cost $12 per pound, walnuts cost $9 per pound, and raisins cost $5 per pound. Donna has $15 to spend on the trail mix. Determine how many pounds of trail mix she can make.
-------
Quantity = x + 2x + 3x = 7x
----
Value = 12x + 9(2x) + 5(3x) = 1500 cents
-------
12x + 18x + 15x = 1500 cents
45x = 1500 cents
x = 33 1/3
-----
almonds = x = 33 1/3 lbs
walnuts = 2x = 66 2/3 lbs
raisins = 3x = 100 lbs
----------------------------
Total weight of train mix = 200 lbs
----------------------------------------
