Jane runs a small farm.  She has 10 chickens that lay 6 eggs each per week. She can sell the eggs for $2/dozen.  How much money will she make in 2 weeks if she sells all her eggs?
Jane's chickens lay 10 chickens * 6 eggs = <<10*6=60>>60 eggs per week.
Jane's chickens lay 60 eggs / 12 = <<60/12=5>>5 dozen eggs per week.
Each week that Jane sells her eggs she can make 5 dozen * $2 = $<<5*2=10>>10 per week.
In two weeks Jane would make 2 * $10/week = $<<2*10=20>>20.
