To solve the exercise, we can use a rule of three, like this:


\begin{gathered} 1\text{ CAD }\rightarrow0.77\text{ USD} \\ 204\text{ CAD }\rightarrow x\text{ USD} \end{gathered}
\begin{gathered} x=\frac{204\text{ CAD }\cdot\text{ 0.77 USD}}{1\text{ CAD}} \\ x=\frac{204\cdot\text{ 0.77 USD}}{1} \\ x=\frac{204\cdot\text{ 0.77}}{1}\text{ USD} \\ x=(157.08)/(1)\text{ USD} \\ x=157.08\text{ USD} \end{gathered}

Therefore, $204 Canadian dollars are $157.08 U.S. dollars using the given exchange rate.
