Answer:20%Step-by-step explanation:% of error is given by the following formula: % Error = [tex]\frac{|\textrm {Approx Value  - Exact Value}|}{\textrm {Exact Value}} \times 100[/tex] Now, Jessie estimated the weight of his cat to be 12 pounds i.e. Approximate value is 12 pounds. Again, The actual weight of the cat is 15 pounds i.e. the exact value is 15 pounds. Therefore, the % error = [tex]\frac{|12 - 15|}{15} \times 100 = \frac{3}{15} \times 100 = 20[/tex]% (Answer)
