Way to Survey-Way to make money at home, paid surveys

I have found a website which can make a person money upto 1 billion dollars? But it is $10 to join for membership and it guarentee earning. We have to reffer people to it and we get $1 for it. Like then if we reffer people 1 billion to it we can get 1 billion dollars? My question is that is it true that a person can earn money upto $1000000000 on working on websites??
It requires e-gold account and there are 41 members active on that site

I dont remember but that code helped
me beat the game. If you have this code please tell me.

Are they all a scam?

that for each $1 decrease in the ticket price, the airline will gain 50 passengers.

1. Express the number of passengers per month, N, as a function of the ticket price, x.

2. Express the monthly revenue for the route, R, as a function of the ticket price, x.

1. N(x)=

2. R(x)=

I need opinions with experience in both please and thanks.

Cable company is Comcast if that makes a difference.
