conversations.value: Faith's neighborhood, with a total of 20 homes, decided to install solar panels. Each home needed 10 panels capable of providing their power needs. The supplier of the panels brought 50 panels less than the required amount. The neighbors agreed to only install the panels up to where they'd be finished. How many homes had their panels installed?

conversations.value: The total number of panels required is 20*10 = 200 panels.
  When 50 failed to be delivered, the total number available for use became 200-50 = 150 panels.
  If each home requires 10 panels, the number of homes that had panels installed is 150/10 = 15 homes
