conversations.value: On the night of the dance 70/100*400 = 280 students who showed up to the party were invited.
  If 40% of those invited to the party had their invitation revoked, there were 40/100*280 = 112 students who showed up and had their invitation revoked.
  The number of invited students who attended the party is 280-112 = 168
