My teacher directed us to Chapter 6 straight up. We didn't even look at Methods in Algebra which I think is mostly revision?

Well, basically 9000 represents 120% of the original price, so you just divide 9000 by 120 to get what 1% of the original price was, and times that by 100 to get the original price

I just did:
x*1.2 = 9000
x=9000/1.2
=\$7500

Is that what you were looking for? If not I'm pretty bad with percentages too XD

we have to get through like 4 chapters of "assumed knowledge"work before we can start the extension stuff and we have like 3 weeks to do it :/ im actually so scared about extension maths because ive had such a crappy teacher the past 3 years that even though i studied as best as i could, i literally failed my yearly exam last year
