Answer the following question.
Grayson has 100 questions on a test. He answers some of the questions for 2 hours, taking two minutes for each answer, then realizes he doesn't know the rest of the questions. How many questions does Grayson leave unanswered when he submits his test?
Step-by-step reasoning process: Each hour contains 60 minutes, so after 2 hours he took 2 * 60 = 120 minutes. If each question takes two minutes, then he answered 120 / 2 = 60 questions. Unanswered questions is 100 - 60 = 40 questions.
The answer is 40.

Answer the following question.
Harris feeds his dog 1 large organic carrot over the course of 1 day. There are 5 carrots in a 1 pound bag and each bag costs $2.00. In one year, how much will Harris spend on carrots?
Step-by-step reasoning process: His dog gets 1 carrot a day and there are 365 days in a year, so his dog eats 1 * 365 = 365 carrots. There are 5 carrots per bag and he will need 365 carrots, so that's 365 / 5 = 73 bags of carrots. The bags cost $2.00 and he will need 73 bags so that's $2 * 73 = $146.00 worth of organic carrots.
The answer is 146.
