You can put this solution on YOUR website! This here is simple math. I do not know your math level, but when you get to more advanced classes such as geometry or Adv. Algebra (Algebra 2), they will give you a simpler way to solve these types of questions. However, I'll just go over the basics.
So, your first year, you get one dollar.
$1
Your 2nd, you get two.
$1 + $2
Your 3rd you get four.
$1 + $2 + $4
Your 4th you get eight.
$1 + $2 + $4 + $8
Your 5th you get sixteen.
$1 + $2 + $4 + $8 + $16
Your 6th, you get thirty- two.
$1 + $2 + $4 + $8 + $16 + $32
7th: $64
$1 + $2 + $4 + $8 + $16 + $32 + $64
8th: $128
$1 + $2 + $4 + $8 + $16 + $32 + $64 + $128
And you continue doubling the numbers until you get to your 18th year.
In total, the answer is $131,072. [Lots of money ;)]
