A natural food store makes its own brand of trail mix out of dried apples, raisins, and peanuts. One pound of the mixture costs 3.18. It contains twice as much peanuts by weight as apples. One pound of dried apples cost $4.48, a pound of raisins costs $2.40, and a pound of peanuts cost $3.44. This is a three variable system. I represented x=apples, y=raisins, z=peanuts.
