Answer:
D. About 90%
Step-by-step explanation:
The top 1% holds about 35% of the wealth, and the next 19% hold about 55%.
35+55 = 90%
So the top 20% hold about 90% of total wealth.
Another way to calculate this is to notice that 80% of people hold 10% of the wealth, so you could make (x= percentage of people) and subtract the remaining percentage of wealth. So:
(80% of people - x% of people) = (100% total wealth- 10% already taken)
x= 90%
