er hi,
Yixuan here.
calculating how much money we must donate to class fund
for the birthday thingy :D
lets say .... 1 cake cost about $30.
okay so if 7 - 8 people share one cake.
7 7 8 8 8 <-- groups of people eating one cake
we'll need like..
5 cakes a celebration.
5 x $30 = $150
$150 x 4 = $600 ( per year )
wow thats alot sia.
$600 divide by 38 = $15.70
so for the 4 celebrations a year, u all need to pay $15 each.
thats if 7 to 8 people share one cake.
cos i not sure if 7 people can finish one cake or not..
the slice like quite big to me.. LOL.
so lets calculate another way.
1 cake cost about $30
9 - 10 people share a cake.
9 9 10 10 <-- groups of people eating one cake.
then.. 9 x 4 = 36
4 x $30 = $120
$120 x 4 = $480 ( per year )
$480 divide 38 = $12.60
so is $12 per person.
9 to 10 people share one cake can ma?
LOLS. kay.
gota go :D
hope tis will help u poll easier.
