Step-by-step explanation:
The percentage error formula is given by :-
Given : The estimated weight of a substance = 475 mg
The actual weight of the substance = 445 mg
Then,
Hence, the percentage error in the first weighing. = 6.416%
Percent means parts out of 100, remember that
12% off
12% off means 100%-12%=88%
find 88% of that
then take 3% and addd that
3% off of 100=100+3=103% of that
then
so original price=p
find 88% of that then 103% of that
p*0.88*1.03=final cost
p*0.9064=final cost
0.9064p=final cost
