George is thinking about doing speculating in interest rates. He thinks rates will fall and, in response, the price of Treasury bond futures should move from $93,$ in their present quote, to a level of about $96\text{'}4.$ Given a required margin deposit of $$1,155$ per contract, what would George's return on invested capital be if prices behave as he expected?

$294\mathrm{.}37\%$

$303\mathrm{.}03\%$

$281\mathrm{.}39\%$

$270\mathrm{.}56\%$
