My taskMy task is to provide a quote of how much it will cost to paint 5
basketball courts. This quote will go to the head of logistics of a large sports complex and he will make a decision as to which quote will be used on completion of the task. The logistics officer will be considering the cost, quality of workmanship and would naturally expect that the quote is well organized and easy to read. He would be expecting to check your mathematical working to ensure that your costs have been formulated accurately. He has informed the school that he expects the job to be completed in less than 3 eight hour days.

ReflectionMy final quote appears to make sense because I know my formulas were
correct (I think) and I did some pretty easy workings that made sense. I measured the court once using a measuring wheel and sometimes the
measuring tape butt the measurements looked accurate. Even if I tried to be accurate, I didn’t really need to because in this case, having 1 or 2 liters of paint more isn't too much of a problem. Nevertheless, I think I should at least try to be accurate so it isn't completely off
I chose to measure the court myself, not using the internet because I was never sure if the results on the internet were true, and If they were, if they were the same as our court.
Some of my workings weren't correct, I might have multiplied by 2, or forgot to add a number but I think it is accurate enough for my results not to be too much out.
