  1. s = the number of sodas sold

    h = the number of hot dogs sold

    A vendor sold a combined total of 252 sodas and hot dogs means:

    s + h = 252

    The number of sodas sold was three times the number of hot dogs sold means:

    s = 3 h

    Put this value in equation:

    s + h = 252

    3 h + h = 252

    4 h = 252

    h = 252 / 4

    h = 63

    s = 3 h

    s = 3 ∙ 63

    s = 189

    63 hot dogs and 189 sodas
