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
