Maths teacher is stupid?

Question

Q-if you had 1000 bacteria and you increased at 200%, how many would you have?

A- the answer is 3000

now my maths teacher believes that it actually equals 2000 but that is wrong

RIGHT?

please tell me that am right and that the answer is 3000

thanks

Answer 1

To simply ask what is 200% of 1000 gives you 2000.  But this question seems to imply a rate of increase.. I think this would have to include a time factor (as:  200% over 5 minutes, or 10 minutes).  Maybe you could re-post with the exact question.  

Answer 2

Yes, your phrasing is a bit hard to understand exactly, but if I take your meaning correctly, then you are right.

An increase of 100% is a doubling, and an increase of 200% is a tripling, each of the original amount. However, be careful, because considering just the increase, not the original amount, you get your teacher's answer. You may have a miscommunication only, and nobody is wrong.  

Answer 3

if u take 200% of 1000 bacteria u get 2000.and then if u plus this 2000 with the 1000 bacteria u'll get 3000.

Answer 4

your math teacher is not stupid he/she is right

-you should always listen to your teachers-

Answer 5

Huh! Im not good with math.

Answer 6

No.  100% of something is the total amount.  So if you get 100% in a test you get all the marks.  So 100% of 1000 bacteria is all the bacteria (1000 bacteria).  That means 200% of 1000 bacteria is double all the bacteria (2000 bacteria).

Do you understand now?

If you don't understand your teacher you should ask him/her to explain more clearly.
