John runs a website that gets 30000 visits a month, for a normal 30 day month. He gets $.01 per visit. How much does he make per day? Give the rationale and then the answer.
Let's think step by step. He gets 30,000 / 30 = 1,000 visits per day. So that means he makes 1000 * .01 = $10 per day.. The answer is: 10.

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? Give the rationale and then the answer.
Let's think step by step. 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.

There are 90 students who have lunch during period 5. Today, two-thirds of the students sat in the cafeteria, while the remainder sat at the covered picnic tables outside. But some yellow-jackets were attracted to their food, and so one-third of the students outside jumped up and ran inside to the cafeteria, while 3 of the students in the cafeteria went outside to see what all the fuss was about. How many students are now in the cafeteria? Give the rationale and then the answer.
Let's think step by step. Originally, there were 90 * 2 / 3 = 60 in the cafeteria. Originally, there were 90 - 60 = 30 outside the cafeteria. Then 30 * 1 / 3 = 10 ran inside. The number of students inside the cafeteria grew by 10 - 3 = 7. There are now 60 + 7 = 67 students in the cafeteria.. The answer is: 67.
