Samantha bought a crate of 30 eggs for $5. If she decides to sell each egg for 20 cents, how many eggs will she have left by the time she recovers her capital from the sales?
There are 100 cents in each $1 so $5 gives 5*100 cents = <<5*100=500>>500 cents
To recover her capital of 500 cents from a selling price of 20 cents per egg she has to sell 500/20 = <<500/20=25>>25 eggs
There were 30 eggs in the crate to start with so she will have 30-25 = <<30-25=5>>5 eggs left
