<PRE><B>Question 936403</B>
charge is $6.50 per pound.
scale is accurate to within plus or minus .03 pounds.


the weight could therefore be .97 pounds to 1.03 pounds.


the customer is paying $6.50.


if .97 pounds, then the customer is paying $6.50 / .97 = $6.70 per pound rather than $6.50 pound.


if 1.03 pounds, then the customer is paying $6.50 / 1.03 = $6.31 per pound rather than $6.50 per pound.
