A) \(\frac{3x+y+2z}{xyz}\)
B) \(3x+y+2z\)
C) \(\frac{3x+y+2z}{6}\)
D) \(6(3x+y+2z)\)
E) \(\frac{x}{3}+ y + \frac{2}{z}\)
A) \(\frac{3x+y+2z}{xyz}\)
B) \(3x+y+2z\)
C) \(\frac{3x+y+2z}{6}\)
D) \(6(3x+y+2z)\)
E) \(\frac{x}{3}+ y + \frac{2}{z}\)

3 pounds of nuts that cost x dollars per pound
Cost of 3 pounds of nuts = 3x
1 pound of chocolate that costs y dollars per pound
Cost of 1 pound of chocolate = y
2 pounds of dried fruit that costs z dollars per pound
Cost of 2 pounds of dried fruit = 2z
Total cost = 3x + y + 2z
Total weight = 3 + 1 + 2 = 6
What is the cost in dollars per pound for the trail mix?
Cost per pound = (total cost)/(total weight in pounds)
= (3x + y + 2z)/6
Answer: C

Brent
