As Adam traveled across the state of Tennessee, he stopped and bought gas, a bottle of soda, and a bag of corn chips at a small store that he will probably never visit again. What type of transaction did Adam engage in when he made these purchases?

Solo exchange.

Explanation:

Solo exchange is a type of market exchange where there is a short time horizon for the customer-salesperson relation or interaction. This exchange is conflicting in nature, involving a bargain system.

It involves no bonds or any interest in the other party. Consisting of a simple transaction, this short term interaction involves the parties caring about their interests. So, when Adam bought the items from a small store that will never be revisited constitutes a form of solo transaction.
