    Answer:

    85 + z <= x <= 255 + z

    Step-by-step explanation:

    An inequality system will be given by a lower limit and an upper limit, therefore it is only necessary to raise an equation for each case, h being the hours worked and z the extra money you can earn by delivering the pizzas:

    For the lower limit:

    8.5 * h + z, knowing that in this case it is 10 hours.

    85 + z would be the lower limit value

    For the upper limit:

    8.5 * h + z, knowing that in this case it is 30 hours.

    225 + z would be the upper limit value

    Therefore the inequality system would be as follows, let x be the money earned:

    85 + z <= x <= 255 + z

    Which means that the money earned will be determined by the previous inequality.
