Answer:
$5.
Step-by-step explanation:
The USD amount when the invoice was generated is $1,168
€1,000 * $1.16849/ € = $1,168
The USD amount on the year end when exchange rate is updated is $1,163
€1,000 * $1.163061/ € = $1,163
The net realized exchange gain/loss is ($1,168 - $1,163) = $5.
The currency quotes are given in the direct quote so we multiply by the invoice amount.
