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. <ibo> Otu afọ na-agba ọsọ bụ otu ụbọchị nke dị mkpụmkpụ karịa afọ nkịtị, n'ihi ya, ọ bụ 365 <unk> 1 = ụbọchị 364.
