Assume a firm's production process requires an average of 80 days to go from raw materials to finished products and another 40 days before the finished goods are sold. if the accounts receivable cycle is 70 days and the accounts payable cycle is 80 days, what would the operating cycle be?

Amachine purchased three years ago for $720,000 has a current book value using straight-line depreciation of $400,000: its operating expenses are $60,000 per year. a replacement machine would cost $480,000, have a useful life of nine years, and would require $26,000 per year in operating expenses. it has an expected salvage value of $130,000 after nine years. the current disposal value of the old machine is $170,000: if it is kept 9 more years, its residual value would be $20,000. calculate the total costs in keeping the old machine and purchase a new machine. should the old machine be replaced?
