Final answer:

To calculate the total time taken to sharpen three chain saws, the hours for each task are added together, resulting in 17.08 hours.

Step-by-step explanation:

The question involves calculating the total time taken by Freddie to sharpen three chain saws using the Cumulative Approach of Learning Curves. To find the total hours required to complete all chain saw sharpening tasks, we simply need to add up the time taken for each individual task. So, the first chain saw took 7 hours, the second took 5.60 hours, and the third took 4.48 hours.

Therefore, the total number of hours required to complete all chain saws is:

7 + 5.60 + 4.48 = 17.08 hours

Hence, the right answer to the student's question is (b) 17.08 hours.
