My washing machine uses L amount of water to wash X amount of clothes. For every 1 unit increase in clothes, the washing machine will use 10% more water to clean (i.e. For X = X + 1, L = L * 110%.
Write a function howMuchWater (JS)/how_much_water (Python) to work out how much water is needed if you have a N amount of clothes. The function will accept 3 parameters - howMuchWater(L, X, N) / how_much_water(L,X,N)
My washing machine is an old model that can only handle double the amount of X. If N > 2X, return 'Too much clothes'. The washing machine also cannot handle any amount of clothes less than X. If that is the case, return 'Not enough clothes'.
The answer should be rounded to the nearest 2 decimal places.
翻譯：
寫出一個 howMuchWater 函式 有三個參數 L , X , N
用來計算洗衣機的用水量
L 是 標準水量
X 是 標準洗衣量
N 是 你要洗的衣服數量
洗衣機最多可以洗 標準量的兩倍衣服，不得超過。
但是最少不能低於標準量
意思就是 每超過一件要需加上總水量的 10%
超過的第二件就是 再加上加了10%後的10%
