Scott, the treasury manager of Weiland Inc., will soon transfer $$110,000$ using either a wire or an ACH transfer. Currently, the firm$$s bank charges $$15$ per wire and $$0\mathrm{.}50$ per ACH transfer. Since Weiland Inc. is not open on Fridays, Scott is only worried about mid$-$week concentration transfers. Scott believes that the firm$$s current annual opportunity cost rate is $4\%.$ Weiland Inc.$$s lead bank has just offered the firm an earnings credit rate of $0\mathrm{.}5\%$ on account balances $($the RRR is $10\%).$

What is the minimum transfer balance that justifies a wire transfer?
