On a certain day, the height of a young bamboo plant was found to be 40 cm. After exactly one day its height was found to be 41.2 cm. Two different models are used to predict its height exactly 60 days after it was first measured.

• Model A assumes that the daily amount of growth continues to be constant at the amount found for the first day.
• Model B assumes that the daily percentage rate of growth continues to be constant at the percentage rate of growth found for the first day.

(i) Using model A, find the predicted height in cm of the bamboo plant exactly 60 days after it was first measured.

(ii) Using model B, find the predicted height in cm of the bamboo plant exactly 60 days after it was first measured.
