Lizzy: A company has 100 employees. 60% of the employees drive to work. Of the employees who don't drive to work, half take public transportation. How many employees use public transportation to get to work?.
Me: Hmmm, let me think. I think this is the detailed solution:
Drive to work:100(.60) = 60. Don't Drive to work:100 - 60 = 40. Public Transportation:40(.50) = 20 employees. Final answer: 20.
