    Answer: he must work for at least 26.32 hours

    Step-by-step explanation:

    Let x represent the number of hours that Hayden works as a life guard.

    Hayden earns $9.50 per hour as a lifeguard. This means that the amount that he earns for working for x hours would be

    9.5x

    He earns a bonus of $50.00 for taking a training course. If he takes this bonus cost, the amount that he would earn for working for x hours is

    9.5x + 50

    Therefore, the number of hours that he must work to earn at least $300.00 would be

    9.5x + 50 ≥ 300

    9.5x ≥ 300 - 50

    9.5x ≥ 250

    x ≥ 250/9.5

    x ≥ 26.32
