### Instruction: Bob is visiting Japan and he wants to buy a coffee for $200$ yen. If one U.S. dollar is worth $108$ yen, how much money, in USD to the nearest hundredth, does he have to spend for the coffee? (You may use a calculator on this problem.).### Response: I need to find the exchange rate from yen to dollars, which is the reciprocal of the exchange rate from dollars to yen.
That is, if $1$ dollar is worth $108$ yen, then $1$ yen is worth $\frac{1}{108}$ dollars.
So, to find how many dollars $200$ yen is worth, I just need to multiply $200$ by $\frac{1}{108}$.
Using a calculator, I get $200 \times \frac{1}{108} \approx 1.85$.
Rounding to the nearest hundredth, I get $1.85$ dollars.
