The correct answer is E.
Mrs. Walters burns one candle every day and she can make a new one from the remaining wax of seven burnt candles. After 56 days, Mrs. Walters can make 8 new candles. (56 ÷ 7 = 8)
So, she has 13 candles now. After seven days, she burns 7 candles and makes another candle. So, she has 7 candles now. She can burn these 7 candles in 7 days and make a new candle after that for another day.
Therefore, she needs to buy new candles after 71 days:
56 + 7 + 7 + 1 = 71
