This is a problem that people face every day. If you spent 10% of your money on food last year and 20% of your money on food this year, how much did your spending on food increase as a percentage of your money?
You solve this problem the same way you find any other change percentage: subtract the old value from the new value and divide that number by the old value. So, (20%-10%)/10% = 100%. The percentage of your money that you spend on food has increased 100% over last year.
