Problema Solution
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 105-pound trail mix-cashew mixture that will sell for $12 per
pound. How many pounds of each 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
