Toymaker Elves
Author Unknown
Ol' Santa's pack held thirty toys
Made by his elfin crew;
And though none made the same amount,
Each elf made more than two.
The elf named Cher made one more toy
Than the elf who dressed in reds,
But Cher made one less Christmas toy
Than the elf who made the sleds.
Spry Johnny Elf made racing cars.
Five toys were made by Jane.
The elf who dressed in yellow suits 
Made each and every train.
The elf who always dressed in green
Made one-third as many as Sue.
Cute Marcia Elf was dressed in orange,
And one elf dressed in blue.
The elf who made the spinning tops
Made the most toys of them all.
Another perky, smiling elf
Made each and every ball.
Ole Santa's pack held 30 gifts
All tagged for girls and boys,
From the clues you've been given,
Now guess who made what toys!

Hint: there are 5 elves and you need to find out what color they are, 
what they made, and how many toys they made.
