20.) A person attempting to lose weight on a diet weighed 175 lb on a bathroom scale at home. An
hour later at the doctor's office, on a more accurate scale, this person's weight is recorded as
178 lb. Assuming that there was no real weight change in that hour, what is the percent error
between these readings?
