Given the stream of consciousness rationale, provide a reasonable question and answer. Rationale: Maria has 3 x 2 = 6 free flowers from buying 3 dozens flowers. Since each dozen is equal to 12, then Maria bought 3 x 12 = 36 flowers. Hence, she has a total of 36 + 6 = 42 flowers.
 The question and answer:
For every one dozen flowers bought, a customer gets 2 free flowers. If Maria wants to buy 3 dozens flowers, how many pieces of flowers will she have in all?
The answer is 42
