Over a 8 week period, the price of an MP3 player dropped steadily, from $82 to $26. What is the average weekly change in the price of the MP3 player over this period?

Respuesta :

First, I would find the difference of 82 and 26: 82 - 26 = 56.

Since there are 7 days in a week, I'd divide 56 by 7: 56/7 = 8.

Therefore, the average weekly change is $8.
