Answer:
$0.34
Explanation:
2 British pound futures @ $1.42 per GBP will become = $1.42 * 2 = $2.84
total money invested = $2.84
To go short means to sell British pound futures that means the trader was expecting to close out his position at a lower price than he/she entered hence he made a loss
closing out at $1.59 per GBP will amount to $1.59 * 2 = $3.18
His loss in USD = closing out price - total money invested
$3.18 - $2.84 = $0.34
His loss in USD is equal to $0.34
