Question 23cii), did anyone else do it like this..?
i) Find the area of the terrace.
...... = 13.77m2
ii) Tiles are sold in boxes. Each box holds one square metre of tiles and costs $55. When buying the tiles, 10% more tiles are needed, due to cutting and wastage.
Find the total cost of the boxes of tiles required for the terrace.
So you go 13.77 + 10/100x13.77 = 15.147m2.
So this means that they need 16 boxes, not 15, as it's more than 15 and they can't buy part of a box.
Am i correct..?</SPAN>
That is the one part of General Maths I find weird; the fact that its logical.
In half yearlys I got a question like that wrong, because .4 of a cup doesn't equal a cup so its 15, but then in trials there was a similar thing and I did it logically and my teacher said it was wrong, there were 23 olives or something.
But basically I think its right to do it logically, thats kind of the point, and also, my tecaher is an idiot- I basically had to tecah myself.
Haha.
Having said all that; I aced this exam.
Had 10 minutes to go back over multiple choice and I didn't guess anything.
Feeling heaps confident.
