Q: John gets a bonus that's the same percentage every year. Last year he made $100,000 and got a $10,000 bonus. This year he makes $200,000. How much will John make this year when adding both his total pay and bonus together?
A:
First we need to determine the bonus percentage, which is found by dividing the bonus amount by the amount John made for the year, taking 10,000 / 100,000 = .10, or 10 percent. Then, we take John's earnings from this year and multiply them by the same percentage, taking 200,000 * .1 = 20,000 dollars in bonuses. We then add these two numbers together, for a total of 200,000 + 20,000 = 220,000 dollars. The answer is 220000.
