Enterprise Bank currently requires customers with checking accounts to maintain a minimum balance or pay a monthly fee. Enterprise plans to offer accounts with no monthly fee and no minimum-balance requirement; to cover their projected administrative costs of $3 per account per month they plan to charge $30 for overdrawing an account. Since each month on average slightly more than 10 percent of Enterprises customers overdraw their accounts, bank officials predict the new accounts will generate a profit. Which of the following, if true, most strongly supports the bank officials prediction? ["Some of Enterprise Bank's current checking account customers are expected to switch to the new accounts once they are offered.", 'Customers whose checking accounts do not have a minimum-balance requirement are more likely than others to overdraw their checking accounts .', 'Customers whose checking accounts do not have a minimum-balance requirement are more likely than others to write checks for small amounts .', 'Many checking account customers who occasionally pay a fee for not maintaining a minimum balance in their account generally maintain a balance well above the minimum.']
