conversations.value: Three plastic chairs cost as much as a portable table. Five plastic chairs cost $55. If Manny wants to buy one portable table and two chairs, how much will be left in his $100?

conversations.value: Each plastic chair costs $55/5 = $11.
  Two chairs cost $11 x 2 = $22.
  A portable table costs $11 x 3 = $33.
  Manny has to pay a total of $22 + $33 = $55.
  Thus, Manny will be left with $100 - $55 = $45.
