conversations.value: In the first year, Bobby will acquire 16 * .5 = 8 new cars.
  After the first year, he will have a total of 16 + 8 = 24 cars.
  In the second year, Bobby will acquire 24 * .5 = 12 new cars.
  After the second year, he will have 24 + 12 = 36 cars in total.
  In the third year, Bobby will acquire 36 * .5 = 18 new cars.
  After the third year, he will have 36 + 18 = 54 cars in total.
