You can put this solution on YOUR website!
total contributions are $38*10=$380+$25 or $405.
(2/5) of this or $162 was spent on food.
There is now $243 left.
(1/9) of the was on decoration or $27.
There is now $216 left.
$156 left after drinks.
$28 left after the prizes.
Therefore, the amount spent for the prize is $156-$28=$128.
