Remember sometime ago that Meihang set a really difficult question for the class?
Well, here's the question. You are welcome to post your workings and solutions online here!
Every perfect entry from each group will gain you 200 points.
Mr Tan gets $7000 every month. He spends $130 on water bills and $60 more on electricity bills. He spends $300 on groceries. He spends $409 on food. Every Saturday, he works for his neighbour and earns $6.20. He then gives $30.50 to the orphanage and saves the rest. How much did he save?
So, what are you waiting for? Get your pencils and start working on the sum now!
Competition ends at the end of next Friday, 24/08/2007, at 2359 hours.
Have a blessed weekend ahead!

HI!
I have one question.Is counted$6.20*4 in $7000?If it is,this is my answer:
Electricity+water bills+groceries+food+orphanage-----$130+$60+$130+$300+$409+$30.50=
$1059.50
saved-$7000-$1059.50=$5940.50
He saved $5940.50

Hi,Miss Seow.I have got the answer.Below is my answer!:
$130+$60=$190(electricity bill)
$190+$130=$320
$320+$300=$620
$620+$409=$1029
$1029+$6.20=$1305.2
$1305.2+$30.50=$1065.7
$7000-$1065.7=$5934.3
Statement: He saved $5934.3.
