Thornton Bank's start-up division establishes new branch banks. Each branch opens with three tellers. Total teller cost per branch is $96,000 per year. The three tellers combined can process up to 80,000 customer transactions per year. If a branch does not attain a volume of at least 50,000 transactions during its first year of operations, it is closed. If the demand for services exceeds 80,000 transactions, an additional teller is hired and the branch is transferred from the start-up division to regular operations Required What is the relevant range of activity for new branch banks?
