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
