Let's assume you're considering short selling in the currency exchange market to make money. Your friend, Tom, is willing to lend you either $500,000,000$ Yen, or $$4,200,000,$ with the condition that you return the money to him in one month and share $30\%$ of the profit from the short selling.

Assuming the spot exchange rate when you borrowed the money was $148$ Yen$/$$$,$ you anticipate the exchange rate to be $141$ Yen$/$$ when you return the borrowed money. Let's assume the exchange rate was $141$ Yen$/$$ as you anticipated when you returned the borrowed money.

Calculate your profit after paying $30\%$ of the profit you made from the short selling to Tom.
