Question 1091500
How many $5 in a ton?  It is 4,540,000/5=908000
That many bills weigh 2000 pounds
units you want are pounds/bill
so divide 2000 pounds/908000 bills to get 0.0022 pounds per bill.
-----------------------
$5000000/20=250000 bills
based on the above weight, that would weigh 550.7 pounds, which would not be very portable.
