conversations.value: Solve the math problem: Matt needs to buy new plates for his home.  He only wants to do dishes once a week.  Three days a week it is only him and his son eating and they use 1 plate each.  On the remainder of the days, his parents join them and everyone uses 2 plates that day.  How many plates does he need to buy?

conversations.value: So for 3 of the days, there are 1+1=2 people eating
  So for those days they use 3*2=6 plates
  On 7-3=4 days the parents join them
  On those days there are 2+2=4 people eating
  They use 4*2=8 plates
  So they use 8*4=32 plates
  That means they use a total of 32+6=38 plates
