Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Kalani has twenty candles in her bedroom, twice the number of candles in the living room. Donovan, her brother, brings in 20 more candles he bought from the candle shop. What's the total number of candles in the house?

### Response:
If the bedroom has twice the number of candles in the living room, there are 20/2 = <<20/2=10>>10 candles in the living room.
When Donovan brings in 20 more candles, the total number of candles becomes 10+20+20 = <<10+20+20=50>>50
