See a solution process below: First, we need to determine how much was left before the man spent 20%. We can rewrite this part of the problem as: 10200 is 80% of what? We are using 80% because he spent 20% so the man has 100% - 20% = 80% left. "Percent" or "%" means "out of 100" or "per 100", Therefore 80% can be written as 80/100. When dealing with percents the word "of" means "times" or "to ...
