Systems of Linear Equations

Hello,
I have to solve this problem:
The manager of a bulk foods establishment sells a trail mix for $8 per pound and premium cashews for $15 per pound. The manager wishes to make a 105pound trail mixcashew mixture that will sell for $12 per pound. How many pounds of each should be used?
I figured out that the first equation should be: X + Y = 105
How do I write the other equation? I tried this, but it didn't work: .08x + .15Y = 12
If you can guide me along, I would greatly appreciate it!
Thank you.
