A car has 121,358 miles on its odometer and accumulates an average of 255 more each week. What is the function rule that represents the total number of M miles the car will have on the odometer after w weeks?

A. M (w) = 121,358 + 255
B. M (w) = 121,358w + 225
C. M (w) = 121,358 + 225w
D. M (w) = 121,358w + 255w
