messages.content: The cookies cost 3 x .5 = <<3*.5=1.5>>1.5
  The hamburgers cost $7.3 because 2 x 3.65 = <<2*3.65=7.3>>7.3
  The total cost is $16 because 7.3 + 2 + 1 + 4 + 1.5 + .2 = <<7.3+2+1+4+1.5+.2=16>>16
  The cost is $8 per person because 16 / 2 = <<16/2=8>>8
  Toby has $7 in change because 15 - 8 = <<15-8=7>>7
