conversations.value: Janet filmed a new movie that is 60% longer than her previous 2-hour long movie.  Her previous movie cost $50 per minute to film, and the newest movie cost twice as much per minute to film as the previous movie.  What was the total amount of money required to film Janet's entire newest film?
conversations.from: assistant
conversations.value: The first movie was 2*60=120 minutes
  So this movie is 120*.6=72 minutes longer
  So this movie is 192 minutes
  It also cost 50*2=$100 per minute to film
  So it cost 192*100=$1920
