Question 53682
The paper money we use today is 0.0043 inch thick. Estimate the number of bills you would need to stack to make a pile that is 1 inch thick. 
Let "x" be the number of bills needed.
EQUATION:
0.0043x=1
x=1/0.0043= 232.558...
Rounding up you get x=233 bills
-------------



If you stacked $20 what would be the total value of the money in pile? 
$20(233)=$4660
Cheers,
