Can you help me answer section b. of this question? I already answered section a-1 and a-2 and they came out as right. Just missing part b. My textbook says: "the break-even reduction number of days occurs when the net daily advantage of the system is zero"
Anne Teak, the financial manager of a furniture manufacturer, is considering operating a lock-box system. She forecasts that 500 payments a day will be made to lock boxes with an average payment size of $2,500. The bank’s charge for operating the lock boxes is $.30 a check.

Minimum reduction in time days: ____
