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
