Answer:
option (C) $5 in the U.S. and 3 euros in Italy
Explanation:
Data provided in the question:
Nominal exchange rate, E = 0.80 euros per dollar
Real exchange rate = 
Now,
Real exchange rate = [ Price of good in US ] ÷ [ Price of Good in Italy ]
= 
Here,
PU = Price of US in dollars
PI = Price of Italy in Euros
Thus,
Real exchange in rate
= 
or
= 
hence,
we get
Ratio of Price of a good in US to Price of a Good in Italy = 
or
we can say $5 in the U.S. and 3 euros in Italy
option (C) $5 in the U.S. and 3 euros in Italy
Answer and Explanation:
The computation is shown below;
1. The willing amount to pay for the promise should be less than $20 that represents the time value of money
2. Now the present value is
= Received amount × discounting factor at 6% for 3 years
= $1,000 × 0.839
= $839
3. Now the interest rate is
As we know that
Future value = Present value × (1 + rate of interest)^number of years
$1,000 = $863.84 × (1 + rate of interest)^3
rate of interest =5% approx
