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.
