Answer:
The amount of money the John lost is € 32.5.
Explanation:
John has €500.
In America, the exchange rate is €1 to $1.1
So, €500 = €500 x 1.1 = $ 550
Now, he is not going to America.
In Europe, the exchange rate is $1 to €0.85.
So, $ 550 = $ 550 x 0.85 = € 467.5
Thus, the money lose by John = €500 - € 467.5 = € 32.5
