    The price of fertilizer is $27.5 and potting soil is $5

    Step-by-step explanation:

    I think that you are asking for the price of each bag of fertilizer and potting soil. And here is my answer:

    Given the system of linear:

    3s + 4f = 125 f = 31.25 - 3/4s (1)

    4s + 2f = 75 f = 37.5 - 2s (2)

    Take (1) - (2) we have:

    f - f = 31.25 - 3/4s - (37.5 - 2s)

    0 = - 6.25 + 1.25s

    1.25s = 6.25

    s = 5

    => f = 37.5 - 2 (5) = 27.5

    So the price of fertilizer is $27.5 and potting soil is $5
