conversations.value: Find a solution for this math problem: James visits 20 houses to try and make a sale.  He manages to sell something in every house.  The next day he visits twice as many houses but only sold to 80% of houses.  If he sold two things at each house in each of the two days, how many items did he sell?

conversations.value: The second day he visited 20*2=40 houses
  So he sold things at 40*.8=32 houses
  So in total he sold things at 20+32=52 houses
  That means he sold 52*2=104 things
