Answer

Option (d)

Work Step by Step

RECALL: For the linear function $f(x) = mx + b$: $b$ is the y-intercept, which is the value of the function when $x=0$, and $m$ = slope, which is the average rate of change. The given function has: $ x$ = the number of days the car is driven $m = 40$, the number of miles a car is driven per day $b = 12,500$ miles Thus, the function $N(x)$ that models the situation is: $N(x) = 40x + 12,500$ Therefore, the answer is Option (d).
