Ethan makes beeswax candles. For each candle, he uses 8 ounces of beeswax and 1 ounce of coconut oil. If he makes three less than 10 candles, what will be the combined weight of the candles in ounces? Let's answer step by step:
If each candle is 8 ounces of beeswax and 1 ounce of coconut oil, then each candle weighs 8 + 1 = 9 ounces. Three less than 10 candles is 10 - 3 = 7 candles. Thus, 7 candles, each weighing 9 ounces, will have a combined weight of 7 * 9 = 63 ounces. The answer: 63.
