In answering Question 3b, visualise the scenario. The answer expected is a percentage, not the actual quantity number of computing books. You need to show your working.
In answering Question 4, again visualise the scenario: How much did she give them? How much change was she given? How much did she spend? What was the price of each pair of running shoes?
Again, show your working. This is a question about money, so your final answer should reflect this.
In answering Question 5a, remember that significant figures and decimal places are NOT the same thing.
In writing your answer for Question 5b, write the power of 10x in a superscript format as shown (using the superscript formatter in Microsoft Word).
In answering Question 6a, think about what the discount means. What would have been the full price if there was no discount? How much are they saving? Do take note of the word ‘total’, reflecting how much was paid altogether (as a group) by Patty and her siblings. Show your working. This is a question about money, so your final answer should reflect this.
