Tweaking the Initial Assembly-Line Design From past experience, Toshihiro has found that the initial assembly-line design supplied by the engineers often needs to be tweaked. Consider the following questions that Toshihiro is considering: What is the daily capacity of the assembly line designed by the engineers? Assume that the assembly line has a computer at every position when it is started at the beginning of the day. (Do not round intermediate calculations. Round down your answer to the next smallest integer.) Daily capacity units per day
