Answer this question: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?
If the number of candles in the bedroom is twice the number in the living room, there are 20 / 2 = 10 candles in the living room. When Donovan brings in 20 more candles, the total number of candles becomes 10 + 20 + 20 = 50.
