5. Now we have two simple equations:
1) 100%=21145
2) x%=7572.29
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=21145/7572.29
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
