Answer:
let cost of each pound of trail mix be x any y respectively
For 2 pounds of trail mix and 5 pounds of jelly beans, the total cost is $10
2x +5y = 10.....(1)
For 8 pounds of trail mix and 3 pounds of jelly beans, the total cost is $23
8x +3y = 23.....(2)
2x +5y= 10 ....... × 4
8x +20y = 40.....(3)
8x +3y = 23 ( from (2))
(3) - (2)
17y = 17
y= 1
8x +3y = 23
8x +3 = 23
8x= 20
x= 2.5
Cost for each pound of trail mix= $2.5
Cost for each pound of jelly beans= $1
