Answer:
Lisa's percentage of error regarding the weight of the dog was 57.14%.
Step-by-step explanation:
Given that the German Shepard actually weighs 28 pounds, but Lisa thought the dog weighed 44 pounds, to determine what is the percent error the following calculation must be performed:
28 = 100
44 = X
(44 x 100) / 28 = X
4,400 / 28 = X
157.14 = X
157.14 - 100 = 57.14
Thus, Lisa's percentage of error regarding the weight of the dog was 57.14%.
