ABL Corporation is currently receiving a return of 10% on its investments. The bank is offering them an ECR of 15%. In order to get more value for their money ABL Corp. has decided to take advantage of the higher ECR and use funds from its Money Market Accounts to cover bank service charges.

If ABL already has an average ledger balance of $750,000, how much more do they need to deposit on their account to cover all $10,000 of monthly service charges?
