Question

Can someone please show the steps to converting this currency problem please? Many thanks!!!!

On October 17, 2016, the exchange rate for 1 Mexican peso was $0.053 U.S. If a traveler exchanged $400 (U.S.) for Mexican pesos, how many pesos did they receive? Round your answer to the nearest peso.

Answer 1

`\bf \begin{array}{ccll} peso&US~\$\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 1&0.053\\ p&400 \end{array}\implies \cfrac{1}{p}=\cfrac{0.053}{400}\implies \cfrac{1\cdot 400}{0.053}=p`
