Ok, here's the deal. I had the following math problem:
In 1997-41,344 motor vehicle production in countries outside the United States.
In 1950-2,571 motor vehicle production in countries outside the United States.
What was the percentage increase in motor vehicle production in countries outside
the United States from 1950 to 1997?
I took 41,344 and subtracted 2,571, this gave me a difference of 38,773.
I then took the 38,773 and divided it by 2,571, this gave me 15.08.
I then moved the decimal two places to the right which gave me a total of 1,508%.
My teacher is telling me this is wrong. She said the answer is 15.08% because when you divide the two the answer is all ready in percent form.
Is this right? I thought when you divided it was in decimal form and you had to convert it to a percent???????? Please help, All other probelms I have done this way were right but for some reason this one she says is wrong. Why would this all ready be in percent form if all other problems I do are not?
Thank you for any help you have on this matter.
I had a feeling that I was right. I came up with 1508%. I have been back and forth with my teacher on this and she swears the answer is 15.08%. She said I am not supposed to multiply this by 100 because the answer 15.08 is all ready in percent form. I do my classes online, and it really bugs me that we have been going back and forth for 1 week now, and she is positive that the answer is 15.08%. What really gets me is this is a college teacher! Thanks for all of ya'lls help. I knew I was right, everyone I talked to said the same things. But my teacher just won't see it. I think I'm fighting a losing battle.
