If Stephanie wants to use 1 candle for half of the cupcakes, then she needs 24/2 = 12 candles for half of the cupcakes.
If she wants to use 2 candles for the other half of the cupcakes, then she needs 24/2 = 12 candles for the other half.
So in total, she needs 12+12 = 24 candles for all the cupcakes.
If she currently has 30 candles, then she needs 24-30 = 6 more candles to complete the cupcakes.
#### 6
