**drwls**, Wednesday, January 5, 2011 at 9:13ama. (40 + 36 + 8 + 6 + 2)/5 = ____

(It will not be an integer)

b. If everybody's age increases by 5, so does the average

c. Apply similar logic

d. If everybody's age increases by N, so does the average

Since we are dealing with a fractional average, the ages should have been given to the nearest tenth year. The computed average is probably low. A person who is "6" for example, could actually be 6.9 years old.
