question: Ophelia and Jenna are living in the same apartment building. They each have 2 fewer sofas than chairs. Jenna has 3 times as many chairs as Ophelia. If Ophelia has 20 sofas, calculate the total number of sofas and chairs that they have.
answer: If Ophelia has 20 sofas and 2 fewer sofas than chairs, she has 20+2 = <<20+2=22>>22 chairs.
  Jenna has 3 times as many chairs as Ophelia, a total of 3*22 = <<3*22=66>>66 chairs
  The total number of chairs Ophelia and Jenna have is 66+22 = <<66+22=88>>88
  Since Jenna also has 2 fewer sofas than chairs, the total number of sofas she has is 66-2 = <<66-2=64>>64 sofas.
  The total number of sofas Ophelia and Jenna have is 64+20 = <<64+20=84>>84 sofas
  Together, they have 84 sofas+88 chairs = <<84+88=172>>172
