One of Santa's elves eats too much breakfast during the holiday season. He weighs 27 kg, but each morning he gains 4 kg. He works so hard making toys in Santa's factory each day that he loses 500 g by the evening. If this pattern continues for 12 days, how much does the elf weigh at the end of the 12 days?
Solutions are to be completed by Wednesday December 16th. Please post them into the Maths Challenge Box in the picture book library.
