    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
