Karson is considering switching from depository transfer checks to using wire transfers for sending funds form its local banks to its main bank in Makati. The cost of the wire transfer is $10 more than the cost of depository transfer checks. The change will reduce the total float by 5 days. Karson can earn 12% on the funds released through the more efficient transfer.

If Karson has 25 local banks, what annual sales level will the firm require before the change to wire transfers become profitable? Assume there are 250 business days each year. Use 360 days in a year.
