conversations.value: Reese joined a Pinterest group where members contributed an average of 10 pins per day. The group owner deleted older pins at the rate of 5 pins per week per person. If the group has 20 people and the total number of pins is 1000, how many pins would be there after Reese had been a member for a month?
  Work out the solution step by step.

conversations.value: In a day, the total number of new pins is 10*20= 200.
  There will be 30*200 = 6000 new pins after a month.
  The total number with old pins present is 6000+1000 = 7000 pins
  If the owner deletes five pins every week, the total number of deleted pins in a week is 5*20 = 100 pins.
  After a month, the number of deleted pins will be 100*4 = 400
  The number of pins after the old pins are deleted is 7000-400 = 6600 pins
