You are wondering how many dollar bills you would need to lay end to end to stretch the 40,000-kilometer distance from Earth to the Moon. You find a website that says the answer is 9 million dollar bills. With a quick estimate, what can you conclude about this answer? Group of answer choices A) 9 million dollar bills is way too small (the actual number would be much more than 9 million). If only 9 million dollar bills were needed, each dollar bill would have to be about 4 meters long. B) 9 million dollar bills is way too large (the actual number would be much less than 9 million). If 9 million dollar bills were needed, each dollar bill would have to be about 4 millimeters long. C) 9 million dollar bills is a reasonable order of magnitude estimate. Dollar bills are about 15 centimeters long, so it would only take about 9 million of them to reach the Moon
