conversations.value: Please show me the solution for: Toby is filling his swimming pool for the summer. The pool normally takes 50 hours to fill. He knows his hose runs at 100 gallons per hour. Water costs 1 cent for 10 gallons. How many dollars does it cost to fill the pool?

conversations.value: The pool holds 5000 gallons of water because 50 x 100 = 5000
  Every gallon costs $.001 because $.01/10 = $.001
  It costs $5 to fill the pool because 5000 x $.001 = $5
