Sam is earning money by mowing lawns, while his friend Will is getting paid to tutor. Sam's money can be represented by the function M = 25w + 75, where w is the number of weeks since Sam began working, and M is the total amount of money possessed in dollars. The table models Will's money and earnings.

Sam's rate of change is __________ Will's rate of change.
