Quizplus · Accepted Answer

The midpoint method involves taking the average of the initial and final values and then calculating the percentage change between them. In this case, we are going from 4 lanes to 6 lanes, which is an increase of 2 lanes.

To calculate the percentage change using the midpoint method:
- Average the initial and final values: (4 + 6) / 2 = 5
- Calculate the difference between the final and initial values: 6 - 4 = 2
- Divide the difference by the average value: 2 / 5 = 0.4
- Convert to a percentage: 0.4 * 100 = 40%

Therefore, the percentage change from 4 lanes to 6 lanes using the midpoint method is 40%, which is equivalent to an increase of 66.67%. Rounded to the nearest whole number, the closest answer choice is C) 66 percent.
