    Answer:

    Lower bound=$2.15×10

    Upper bound=$2.25×10

    Step-by-step explanation:

    A milloniare estimates her wealth to be $2.2×10 to the nearst million dollars.

    In other words, his worth is $22 to the nearst million dollars.

    To find the lower bound of the millionaire’s wealth, we divide the level of precision by 2 and subtract from the millionaire’s wealth.

    Lower bound= 22-0.5=21.5 million dollars.

    To find the upper upper bound, we add half of the level of precision to her estimate.

    Upper bound =22+0.5=22.5 million dollars
