Bambang has received a proposal from Metrobank to establish a lock-box system to accelerate the receipt of P500 million annually on 1,000,000 checks. By its own analysis, Bambang believes such a system would decrease total float by 3 days. If Bambang can earn 8 percent before taxes on the released funds, what is the maximum that Bambang should be willing to pay the bank per check for the service?
