The rate of growth for a plant is 0.2 centimeters per 0.5 day. A student found the number of days for the plant to grow 3.6 centimeters to be 1.44 days. Which of the following explains the error and how to correct it? A)
The student found the unit rate of growth to be 0.1 centimeter per day. The unit rate is 0.5. So, the number of days for the plant to grow 3.6 centimeters is 1.8 days.

B)
The student graphed the relationship by graphing the point (0.2, 0.5). By continuing the line from the origin, the student should have found the point (3.6, 36). So, the correct number of days for the plant to grow 3.6 centimeters is 36 days.

C)
The student wrote the equation y = 3.6x to represent the relationship. The student should have used the equation y = 0.2x. The correct number of days for the plant to grow 3.6 centimeters is 7.2 days.

D)
The student created a ratio table and incorrectly placed 3.6 in the row with the number of days. The correct number of days for the plant to grow 3.6 centimeters is 9 days.
