Determine the rate of return (that is, Zack's opportunity cost of funds) at which the costs of the two proposals would be equal % Round your answer to two decimal places Determine the number of payments per month at which the costs of the two proposals would be equal, assuming that the processing fees and compensating balances remain constant Round your answer to the nearest whole number. Enter your answer in whole numbers. For example, an answer of 1.20 million should be entered as 1,200,000, not 1.20
