0.1
the 0 is in the thousandths place plus the 2 os next to is since 2<5 it is 0

For this to be equivalent to

, you require

and

Dividing the second equation by the first gives

Meanwhile, you also get

So,
Answer: b = m
(3 + m)(3 - m)
Step-by-step explanation:
One way to approach this is to know that $5200 is 80% of her savings, so if we divide 5200 by 8 we will get 10% of her savings. 5200/8 = $650.
We can then multiply this by 10 to get 100%, or her total, savings (because 10*10=100)
So, $650*10= $6500
The total savings in dollars is $6500
