    the price for one pretzel was $1.75

    Step-by-step explanation:

    d for drinks

    p for pretzel

    3d + 3p = 9

    3d = 9 - 3p

    d = 3 - p

    replace d = 3 - 9 into 4d + 2p = 8.5

    4d + 2p = 8.5

    4 (3 - p) + 2p = 8.5

    12 - 4p + 2p = 8.5

    -2p = 8.5 - 12

    -2p = - 3.5

    p = 1.75
