    Answer:

    Yes, because the total will be $31.75

    Step-by-step explanation:

    Let

    x —–> number of hours weeding grandmother’s garden

    z —-> number of hours selling seashells at the flea market

    we know that

    The inequality that represent this situation is

    2.25x+5.50z+5.25\geq30

    so

    For x=2 hours, z=4 hours

    substitute in the inequality

    2.25(2)+5.50(4)+5.25\geq30

    4.50+22+5.25\geq30

    31.75\geq30 —–> is true

    therefore

    Janice will have enough to buy the necklace
