    The weather report says the temperature is 20°c and will drop 5°c per hour for the next 6 hours.

    Temperature drops by 5°c per hour

    So we find the temperature after 6 hours

    In 1 hour temperature drops = 5°c

    So in 6 hours = 6 * 5 = 30°c

    In 6 hours, temperature drops by 30°c

    the actual temperature is 20°c. after 6 hours the temperature becomes

    20°c - 30°c = - 10°c

    So, after 6 hours the temperature will be - 10°c

    Daryl plans to be gone for at least 6 hours. so its 6 hours or more than 6 hours

    In 6 hours or more than 6 hours, the temperature will drop less than - 10°c.

    So, Daryl should move his plant to a warmer location before leaving

    An inequality to model the problem is

    ✔ 20 - 5x > - 10

    .

    The solution is

    ✔ x < 6
