Last week, Ms. Hoffman asked you how to convert Turkish Lira to US Dollars. She told you that the official exchange rate was 1 TL = $0.45. You then figured out how much 15 TL was in dollars. But, I bet you had to use a pencil and paper to figure it out! Ms. Hoffman does not always carry a pencil and paper with her (or even a calculator) when she is traveling. But, she still wants to know how much things cost in dollars. She has to find ways to do the math in her head!
With some different money, the exchange rate was pretty easy, like in South Africa. But, here in Turkey, it is not so easy. Ms. Hoffman might have to use estimation.

Can you think of a way to use estimation to make it easier for Ms. Hoffman???
