The veterinarian weighed Oliver's new puppy, Boaz, on a defective scale. He weighed 46 pounds. However, Boaz weighs exactly 44.5 pounds. What is the percent of error in measurement of the defective scale to the nearest tenth?

The percent error is the absolute difference of the actual and measured values, divided by the actual value, multiplied by 100. In here, the actual value is 44.5 lb, while the measured value is 46 pounds.

Percent error = |44.5 - 46|/44.5 * 100 = 3.37%
