Can I ask you, In the word problem, there were no number to go by, How does a person know to use "100" rather let say "200E or "300E" ? The precentage on this word problem made me think I needed to turn it into a regular number then some how start multiplying. I was so intimidated by the percentages. Thank YOU for taking your time out to solve this problem. I wish I could give you 10,000 points.
