Lizzy: Kelly has 8 chickens that lay 3 eggs each per day. If Kelly sells these eggs for $5 a dozen. How much money will she make in 4 weeks if she sells all her eggs?.
Me: Hmmm, let me think. I think this is the detailed solution:
Each chicken lays 7 * 3 = 21 eggs a week. Each week all the chickens lay 21 * 8 = 168 eggs. In 4 weeks all the chickens lay 168 * 4 = 672 eggs. 672 eggs equal 672 / 12 = 56 dozens. Kelly would make 56 * 5 = 280 dollars. Final answer: 280.
