Final answer:
After calculating and considering the placebo pills, an 84-day supply results in a 63-day supply when skipping placebo pills. However, this answer is not among the options provided.
Explanation:
When we consider a typical contraceptive pill pack, it contains 21 active (hormonal) pills and 7 inactive/placebo pills: the total is 28 pills, representing a typical menstrual cycle. From this, we can identify a standard cycle as lasting for 28 days (21 active + 7 placebo). If you have an 84-day supply of pills and are skipping the placebos, we need to account only for the days with active pills. The number of active pill cycles in 84 days is 84 days / 28 days per cycle = 3 cycles. Therefore, with each cycle having 21 active days, the number of active pill days in three cycles is 3 cycles x 21 days per cycle = 63 days. Therefore, the day supply left when skipping placebo pills is 63 days, which is not an option among A. 14 days, B. 42 days, C. 56 days, D. 84 days.
