Problema Solution
The manager of a bulk foods establishment sells a trail mix for $9 per pound and premium cashews for $15 per pound. The manager wishes to make a 108 pound trail mix-cashew mixture that will sell for $14 per pound. How many pounds of cashews should be used?
Answer provided by our tutors
The trail mix: x
The premium cashews: y
The equation is
x+y = 108
9x+15y = 14*108
So
x =18
y = 90
So premium cashews: 90 pounds
