Hey, i've decided to give myself some things to work out., in preparation for my Exam. Obviously it's not any questions from the exam, how would i have got a hold of them? They may seem easy, but some people do happen to beDyslexic:

I originally posted this in another forum, but they obviously didn’t get what I mean:I posted that this was NOT homework. I had set myself a question to answer, and i wanted to find out HOW!

People immediately presume, that every question that resembles these ones must be homework =[

Peter works as a real estate agent and is paid commission at a variable rate. He receives 4% on the first $100 000 of sales, 21/2 % on the next $100 000 of sales and 11/2% on the remaining balance of sales. If peter sell’s a house for $349 000 how much will he be paid?

Monica knows that the selling price of a walkman is $89.95. She also knows that this price includes a mark up of 10%. What was the original price of the walk-man?

(Potentially you would go like this if it was not a mark up) 89.95 x 10% (without having to use the =’s sign)

And: The Numbers in the left column have been changed to the numbers in the right column. Determine the percentage change and state whether it was an increase or decrease.

3452 ----- 43156060 ------- 2908.8

I have already established that both have been increased? But I’m not sure about these percentage changes =[
