### 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 want to find how many dollars are equivalent to $200$ yen.
I can use the given exchange rate to set up a proportion: $\frac{1}{108} = \frac{x}{200}$, where $x$ is the amount of dollars I need.
I can cross-multiply and get $108x = 200$.
I can divide both sides by $108$ and get $x = \frac{200}{108} \approx 1.85$.
I can round my answer to the nearest hundredth and get $x \approx 1.85$.
