Hi Class 9,

I haven't been able to get you work up until this morning (Wed 17th). Wherever you are up to, please try 1J - simple interest. All of you should be able to do this chapter.

I have included a pdf of the appropriate chapter pages and answers. Be wise with what you print out - you may not need all of it!

I have also included a video showing:

 - what questions to do

 - how to get the formula and

 - an example.

It goes for ~ 10 mins.

Let me know if you need help.
