Answer:

Step-by-step explanation:

Change 69% to a decimal so divide by 100 and it gives you 0.69.
then times that number by $503.68 which gives $347.54
.56 because 4 x 14 = 56 then 56 / 100 = .56
Answer:
There is 10% error in both minimum and extreme values i.e. 120 & 140 , Error in 120 is 10% i.e. = 12, Since value can be more or less in error ∴ Error in 120 is ±12.
