A bottle of shampoo lasts her 14 / 1 / 4 = 14 * 4 = 56 washes. If she buys 3 bottles, she will only have enough for 56 * 3 = 168 washes. If she buys 4 bottles, she will have enough for 56 * 4 = 224 washes. Since 168 < 182 and 224 > 182, Brittany needs 4 bottles of shampoo to get her through a leap year. So the final answer is 4. <hau> Shekarar da ba ta cika ba ta fi shekara ta yau da kullum da kwana ɗaya, saboda haka, kwana 365 <unk> 1 = 364.
