    All positive rational numbers greater than 50

    Step-by-step explanation:

    Since the delivery cost is fixed per trip, the cost incurred can be represented by the equation

    y (x) = 8x+50 so in case Tess wants only 1 tone, the cost will be y (x) = 8 (1) + 50=58

    Therefore, it's proper to conclude that all numbers in the possible range are positive rational numbers greater than 50
