Answer: 200% increase
Step-by-step explanation:
Being an increase from 12inches to 36inches, we will calculate the percentage increase.
%increase = final length -initial length/initial length × 100%
Initial length = 12inches
Final length = 36inches
%increase = 36-12/12 × 100%
%increase = 24/12 × 100%
%increase = 200%
Answer:
200% increase
Step-by-step explanation:
percent change = [(difference between initial and final value) ÷ initial value] x 100
⇒ percent change = [(36 - 12) ÷ 12] x 100 = 200% increase
