conversations.value: Very early this morning, Elise left home in a cab headed for the hospital. Fortunately, the roads were clear, and the cab company only charged her a base price of $3, and $4 for every mile she traveled. If Elise paid a total of $23, how far is the hospital from her house?

conversations.value: For the distance she traveled, Elise paid 23 - 3 = 20 dollars
  Since the cost per mile is $4, the distance from Elise’s house to the hospital is 20/4 = 5 miles.
