Question

Every month, a company issues a cheque to pay for inventory. The average payment amount is $71,595. It takes 7 days for the cheque to clear. Currently, the company earns 0.028% per day on any cash balance in its bank account. The company has an option to switch to another bank, where the cheque would now take 10 days to clear, but the company would be able to earn a daily interest of 0.039%. If the company decides to switch, what is the absolute value of the net monthly interest that the company will gain or lose as a result?
