Question: John wants to lose weight. He eats 1800 calories a day and burns 2300 a day. If he needs to burn 4000 calories to lose 1 pound how many days will it take to lose 10 pounds? Think carefully first, then make a decision:

He burns 2300 - 1800 = 500 calories a day. He needs to burn 4000 * 10 = 40,000 calories to hit his goal. That means it will take him 40,000 / 500 = 80 days. So the answer is 80.
