The Challenge -  
 
 

A Ziggurat wasn't built in a day

As ruler of a Sumerian city you have 180 workers to build a three staged ziggurat. Your challenge is to divide them between different jobs. If you have too many people making bricks but not enough people digging the clay, brick making will stop. If you don't have enough workers laying bricks the ziggurat will never be completed. Work out the best combination to please the gods
