For number 1: you would add all the ages together, 23+19+50+49+67+34+30+59+40+33=404 and then divide that by how many workers(10) 404 divided by 10=40.4 and that is already rounded to the nearest tenth. So the answer to number 1 would be C. 40.4. Number 2: I'm just guessing but because the line on the graph shows is at around B) and C) is looks closer to $122 million, so I would go with D. $122 million
