Please answer quick I need to get this for my mock test

I think 64.29 bc 90 percent of 500 is 450 so i did 450 percent of 700

The answer would be 126 choose any steps you want that I will write now

First steps:

- 90/500 = x/700
- 18/100 = x/700
- x = 18.7 = 126

Another steps:

- 700/500 = 7/5
- ( 7/5) • 90 = 7•90 / 5 = 7.18 = 126

Your maths is very weak try yourself this would improve your skills don't depend on others

The answer simplified would be. -6300x
