companies?

  37 weeks

Step-by-step explanation:

Assuming she worked 5 days per week, the number of companies visited each week is ...

  (7.5 h/da)(60 min/h)(5 da/wk)/(25 min/company) = 90 companies/week

Then the number of weeks required to visit 3276 companies is ...

  (3276 companies)/(90 companies/wk) = 36.4 wk

The executive spent 37 weeks visiting all those companies.

It was 36 weeks and 2 days, so was more than 36 weeks. It wasn't quite 37 full weeks.
