A New Yorker travels to New Jersey to buy a $100 telephone answering machine. The New Jersey company that sells the machine then deposits the $100 check in its account at a New York bank. How would these transactions show up in the balance of payments accounts of New York and New Jersey? What if the New Yorker pays cash for the machine?

I got confused with this one and thought the transaction would not be recorded in the balance of payment because it doesnt say that the new jersey company is owned by a foreign resident. Since both New York and New Jersey are within the same country, the transaction would not involve any international trade or financial flows that affect the balance of payments of the United States. Thats what I thought but I am not sure
