Answer:
The gain is of $17.50
Step-by-step explanation:
When you buy the bond the exchange rate is $1.50 = £1.
You pay £45 = [tex]1.50\times45[/tex]=$67.50 for the British bond.
No, you sell the bond for £50 and the exchange rate is $1.70 = £1.
So, you earned [tex]50\times1.70=85[/tex] dollars
Your gain is [tex]85-67.50[/tex] = $17.50
