Quite, Diane. I make it 102 + 11 + 1 + 1 = 115.

What!??? surely if you melt down the 102 you can make another 102 for ever unless you somehow factor breakdown of the material. Where are you getting your figs from please? I'm confused

Oh I just realised. You are burning the 102 candles then using the stubs to make the other ones. Clever stuff.

921 stubs = 102 new candles with 3 stubs over
102 stubs +3 = 105 stubs = 11 new candles with 6 stubs over.
11stubs + 6 =17 stubs = 1 new candle with 8 stubs over
1 stub with 8 left = 9 stubs = 1 new candle.
SO ! total = 102 +11 +1 +1 which is 115 candles with 1stub left.
