We have a process with four steps; each step occurs in order. All product must go through each step. Each product can be sold for $$40$ per item; the process operates for $16$ hours a day, $220$ days a year.

Each workstation can work on one item at a time. The number of workstations for each step, as well as the flow time for each step, is given here:

Step # of workstations Flow time $($min$)$

$117$

$2416$

$3514$

$449$

Given the above information, how much annual revenue can the process generate, in dollars per year? $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$
