Q: Lao is farming chickens. He can sell each chicken for $1.50. A bag of chicken feed weighs 20 pounds and costs $2. Each chicken will need 2 pounds of feed from the time it hatches to the time he sells it. If he makes $65 profit from selling chickens, how many did he sell?
A: 50
Step-by-step reasoning process: A bag of feed is enough for 10 chickens because 20 / 2 = 10. Each chicken costs $.2 to raise because 2 / 10 = .2. Each chicken results in $1.3 of profit because 1.5 - .2 = 1.3. He sells 50 chickens because 65 / 1.3 = 50.


Q: A candy store uses food colouring in various candies. Each lollipop uses 5ml of food colouring, and each hard candy also needs food colouring. In one day, the candy store makes 100 lollipops and 5 hard candies. They do not use food colouring in anything else. The store has used 600ml of food colouring by the end of the day. How much food colouring, in millilitres, does each hard candy need?
A: 20
Step-by-step reasoning process: In total, the lollipops needed 5ml of food colouring * 100 lollipops = 500ml of food colouring. This means that the hard candies needed 600ml total food colouring – 500ml food colouring for lollipops = 100ml of food colouring. So each hard candy needed 100ml of food colouring / 5 hard candies = 20 ml of food colouring.


Q: Yasna has two books. One book is 180 pages long, and the other book is 100 pages long. If Yasna wants to finish both of the books in two weeks, how many pages will Yasna need to read every day, if she reads an equal number of pages each day?
A: 20
Step-by-step reasoning process: The total number of pages is 180 + 100 = 280 pages. The number of pages Yasna needs to read every day for two weeks is 280 / 14 = 20 pages.


Q: Susie's pet lizard Moe takes 10 seconds to eat 40 pieces of cuttlebone each day. How long would it take Moe to eat 800 pieces?
A: 200

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Step-by-step reasoning process: If it takes Moe 10 seconds to eat 40 cuttlebones, then in one second she eats 40 cuttlebones / 10 seconds = 4 cuttlebones / second. Since the cat eats 4 pieces of cuttlebone in 1 second, 800 pieces will be 800 cuttlebones / 4 cuttlebones / second = 200 seconds.
