@xxLagoonxx,
Quote:Final amount after everyone eats: 878912
878912 / (1-0.075) = Amount before Jetsam
Amount before Jetsam / (1-0.012) = Amount before Buzz
To think of it another way,
Final amount = Amount before Jetsam - Amount Jetsam eats
Now the amount the Jetsam eats is 7.5% of what is there before he eats. We can express 7.5% as a decimal .075, so
Amount Jetsam eats = .075 * Amount before Jetsam
Substituting this in,
Final amount = Amount before Jetsam - .075 * Amount before Jetsam
Final amount = 1 * Amount before Jetsam - .075 * Amount before Jetsame
Final amount = (1 - .075) * Amount before Jetsam
