Basic Econ Problems Hi guys, I am doing a study guide provided by my professor, and I am getting very different answers from the answers he provides. He is not the easiest professor to contact (speaks a different language and rarely checks his email). problem 1 http://i1345.photobucket.com/albums/...ps7aaeb95a.png problem 2 http://i1345.photobucket.com/albums/...ps7acb2fd1.png So far I was getting everything right in the study guide, but these problems seriously have me worried that I am not prepared for the exam tomorrow. He is known to make a lot of mistakes in the past, so I am not sure if it is my answers that are wrong or his. Please help! What answers are you guys getting for these and why?

Basic Econ Problems Are you serious...looks too easy to be true Your 1st link show this column: 0: 0 1: 100 2: 300 3: 600 4: 1000 5: 1500 6: 2100 7: 2800 8: B 9: 4500 10: 5500 You're asked to pick one of these as describing above: a) decreasing at constant rate b) decreasing at decreasing rate c) increasing at constant rate d) increasing at increasing rate WHY a) and b) ? Anyone can see the darn thing is increasing! Easy to see increases are 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 So not c) ; therefore answer is d) PLUS if you're asked for B's value, you can easily tell it's 2800 + 800 = 3600, right? Is your teacher REALLY getting these wrong?

Looks more like "would someone answer this question for me" -- which you did -- to me.
