messages.content: This year’s total production is 5000 * 2 = <<5000*2=10000>>10000 phones.
  A quarter of this year’s production is 10000 / 4 = <<10000/4=2500>>2500 phones.
  The number of phones left after selling a quarter of the production is 10000 – 2500 = <<10000-2500=7500>>7500 phones.
  #### 7500
