The cost for each pound of trail mix and each pound of jelly is given below.
Step-by-step explanation:
Let t = cost/pound of trail mix
Let j = cost/pound of jelly beans
5t + 6j = 35 
3t + 2j = 15  =  > 2j = 15 - 3t 
5t + 3(15 - 3t) = 35 
5t + 45 - 9t = 35
 - 4t + 45 = 35
 - 4t  =  - 10 
 4t = 10 
 t = 2.5
 3(2.5) + 2j = 15
 7.5 + 2j = 15 
 2j = 7.5 
 j = 3.75
