Answer:
when customer have over charge - $6.31
when customer have undercharge - $6.70
Explanation:
Given data:
Charge is $6.50/pound.
Scale is accurate to within [tex]\pm 0.03 lb[/tex].
therefore, the weight could be .97 [ 1- 0.03] pounds to 1.03 [1 + 0.03] pounds.
From the information given question we have
The customer is paying $6.50.
if weight is 0.97 lb, the customer paid
[tex]\frac{6.50}{0.97} = $6.70 /lb[/tex] rather than $6.50/ lb.
if weight is 1.03 pounds, the customer paid
[tex]\frac{6.50}{1.03} = $6.31/ lb[/tex] rather than $6.50/lb.
