Suppose that this individual now decides to give one-eighth of a percent (0.125 %) of her new net worth to charity. how many dollars are given to charity?

I believe this question is not complete, however, I'll tell you how to solve this type of questions and you can apply on the numbers you have.

Suppose an individual has an amount of money x and wants to donate 0.125% of this amount to charity

Therefore, to know the amount donated, you can simply calculate it as follows:
amount donated (y) = (0.125/100)*x

The amount left to the individual would then be:
amount left = x - y

To better understand this, I'll just assume that the net worth is $8.22x10^10, therefore:
amount donated to charity = (0.125/100) * 8.22 * 10^10 = $1.0275x10^8
amount left = 8.22x10^10 - 1.0275x10^8 = $8.209x10^10
