this isn't really homework, just something i'm fiddling with.
let's say 100% of all people earn a dollar or more;
and 90% of all people earn 10 dollars or more;
and 50% of all people earn 20 dollars or more;
and 33% of all people earn 30 dollars or more;
and no one earns more than 40 dollars;
can you write an equation that goes though the other values? (can you compute say 2 dollars or more?)

So 10% earn between 1 to 9 (assuming integer values). I don't see anything that says those 10% can't all be making $9 or all making $1 or any mix between.
