Assume you are a trader with Deutsche Bank. From the quote screen on your computer terminal, you notice that Commerzbank is quoting $0\mathrm{.}7677/$$$1\mathrm{.}00,$ and Credit Suisse is offering SFr$1\mathrm{.}1856/$$$1\mathrm{.}00.$ You learn that UBS is making a direct market between the Swiss franc and the euro, with a current $/$SFr quote of $0\mathrm{.}6345.$ Show how you can make a triangular arbitrage profit by trading at these prices. Ignore bid$-$ask spreads for this problem. Assume you have $$5,001,000$ with which to conduct the arbitrage. Enter only the numeric portion of your answer without the currency symbols.

b$-1.$ Describe the sequence of transactions you should undertake to earn a triangular arbitrage profit.

b$-2.$ What is your triangular arbitrage profit?
