Question

The veterinarian weighed Oliver's new puppy, Boaz, on a defective scale. He weighed 36 pounds. However, Boaz weighs exactly 34.5 pounds. What is the percent of error in measurement of the defective scale to the nearest tenth? Explain your answer and show your work.

Answer 1

new amount - original amount = amount of change


`(amount ~of ~change)/(original~amount)` × 100 = percent of change

-----------------------------------------------------------------------------

36 - 34.5 = 1.5


`(1.5)/(34.5)` × 100 = 4%
