完整解法

1. Read the exchange rate on the 6th and convert dollars to Euros

From the graph, on the 6th day,
$1\text{ Euro} = \$1.60.$
So the number of Euros Emmett gets is
$1200 \div 1.60 = 750.$

答案

$750$ Euros

1. Read the greatest and least exchange rates from the graph

From the graph,

Greatest exchange rate $= 1.610$ dollars per Euro

Least exchange rate $= 1.575$ dollars per Euro

2. Find the difference in exchange rate

Difference in exchange rate
$= 1.610 - 1.575 = 0.035$
So the difference is $0.035$ dollars per Euro.

3. Convert the exchange-rate difference to the difference in cost for 120 Euros

Difference in accommodation cost
$= 120 \times 0.035 = 4.20$

答案

$4.20
