You are managing a construction project, and you must determine how long it will take to complete the foundation work. You have data from a similar project showing that the foundation work took 45 days with a team of 5 experienced workers and standard equipment. For the current project, you're planning to allocate 6 workers with similar experience and equivalent equipment. The work will be performed under similar conditions. Assuming a linear correlation between the number of workers and the duration, how many days should you estimate for the foundation work to be completed?
40 days
37.5 days
50 days
45 days
