A Theme Park on the Moon?

This week for Maths we are making a lunar theme park.  We only have 500,000 to spend. We have to decide what rides we can put in are park that will fit into the budget.  There is a twist... we have to pay electricity and staff costs etc. so we need to work out our profits and loss. It's a heap of work but heaps of fun. I hope we can open a Theme Park on the moon one day!   By Claire.
