Question

Problem: Luis is planning a trip to Rome. Before he leaves, he wants to exchange his American money ($) for Euro (€). If the current exchange rate is $1 : €0.84, how much money will he get if he exchanges $75?

Answer 1

We can find the amount of euros using the rule of three

`\begin{gathered} 1\text{ dollar}\rightarrow0.84\text{ euros} \\ 75\text{ dollars}\rightarrow x \end{gathered}`

then:

`x=(75\cdot0.84)/(1)=63`

Therefore he will get 63 euros.
