Your theoretical task on this floor is to construct a model that represents the money flowing in and out of your bank account and helps you predict when you'll be able to afford a DVD recorder. For this purpose, you find a graphical model editor in this room that will help you to build and test models. You can take a look at the data your model produces by using the graph tool and the table tool.
As mentioned in the Introduction to the Model Editor assignment in the hall, your model should be able to calculate when you'll be able to afford a DVD recorder.
If you've completed the introduction assignment, You can then use the Additional Assignment-The Pocket Money Simulation to adapt your model and predict when you'll have a to get a job.
The following help files also exist to assist you in making your models.
