Let \(\displaystyle x\) = number of people (originally).If I know that 65% of people will drop out of a study,
but I want to end up with 450 people at the end of the study.
How many people must I start out with?
Soroban, why could the answer not be 1,285 people or 1,287 people?
I assume we are dealing with "whole" people . . . so we "drop decimals".
