Answer:
Sophie will get <u>$56</u> in exchange.
Step-by-step explanation:
Given:
TravelEz sells dollars at a rate of ($1.40)/(1 euro).
And dollars they buy at a rate of ($1.80)/(1 euro).
Sophie exchanged $540 to get 300 euros, at the beginning of trip.

<em>As, </em><em> is equivalent </em>
<em>.</em>
<em>So, </em><em> is equivalent to </em>
<em>.</em>
Thus,
By cross multiplying we get:
Therefore, Sophie will get $56 in exchange.
