Step-by-step reasoning process: 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 question and answer:

Step-by-step reasoning process: The chickens cost $80 because 4 x 20 = 80. His chickens produce a dozen eggs a week because 4 x 3 = 12. Each week that he has chickens is $1 cheaper than buying eggs because 2 - 1 = 1. After 80 weeks his chickens will be paid off because 80 / 1 = 80. After 81 weeks the chickens will be cheaper than buying eggs because 80 + 1 = 81.
The question and answer:
Question and answer: Roberto is raising chickens for eggs. He buys 4 chickens for $20 each. They cost $1 in total a week to feed and each produces 3 eggs a week that will last forever. He used to buy 1 dozen eggs a week and spent $2 per dozen. After how many weeks will the chickens be cheaper than buying his eggs?
The answer is 81

Step-by-step reasoning process: The boat had 20 - 3 = 17 sheep make it to shore. 3 sheep drowned, so 2 * 3 = 6 cows drowned. 10 cows on the boat - 6 drowned = 4 cows made it to the shore. 17 sheep + 4 cows + 14 dogs = 35 animals made it to shore.
The question and answer:
Question and answer:
A boat carrying 20 sheep, 10 cows and 14 dogs capsized. 3 of the sheep drowned. Twice as many cows drowned as did sheep. All of the dogs made it to shore. How many total animals made it to the shore?
The answer is 35
