Susan, an entrepreneur, wants to sell handmade goods from people in developing countries to customers in the united states. why would it be necessary for there to be a way to exchange currency in order for this to happen? currency exchange would allow susan to accept u.s. dollars, yet still pay the craftspeople in the currency that would be most useful to them. currency exchange will allow the craftspeople to spend u.s. dollars in their home countries. it is not necessary for there to be a system for currency exchange, because most developing countries do not have their own currency. currency exchange would allow susan to directly trade the handmade goods of craftspeople for goods and services that would help them.
