prompt: Wickham is throwing a huge Christmas party. He invites 30 people. Everyone attends the party, and half of the guests bring a plus one (one other person). He plans to serve a 3-course meal for the guests. If he uses a new plate for every course, how many plates does he need in total for his guests?

messages.content: The number of guests that bring a plus one is 30 / 2 = <<30/2=15>>15 guests
  The total number of guests at the party, including the plus ones, is 30 + 15 = <<30+15=45>>45 guests
  Since there are 3 courses, Wickham will need 45 * 3 = <<45*3=135>>135 plates
  #### 135
