How many pounds of nuts selling for $6 per lb and raisins selling for $3 per lb should Theresa Rebello combine to obtain 60lb of a trail mix selling for $5 per lb?
Answer provided by our tutors
Let nuts x
let raisin y
Total quantity 60
X+y=60 which can be written as x=60-y
Cost of nuts is 6
Cost of raisin is 5
Total amount is 5*60=300
6x+3y=300
6(60-y)+3y=300
360-6y+3y=300
3y=60
Y=20
X=60-20=40
