buying and selling globally, Business and Finance homework help

Any company operating globally must deal in foreign currencies. It has to pay suppliers in other countries with a currency different from its home country’s currency. The home country is where a company is headquartered. The firm is likely to be paid or have profits in a different currency and will want to exchange it for its home currency.
