Roger lives in Orlando but just started a new job in Tampa. Every Monday he drives his car 95 miles from Orlando to Tampa, spends the week in a company apartment, and then drives back to Orlando on Friday. He doesn't use his car for anything else. After 20 weeks of this, his odometer shows that he has travelled 84,000 miles since he bought the car. 1.) Write a linear model which gives the odometer reading of the car as a function of the number of weeks since Roger started the new job.
f(x) = __x+__

2.) If he plans to buy a new car when his odometer reaches 100,000 miles, about when will Roger buy his car?
a.) about 104 weeks
b.) about 168 weeks
c.) about 120 weeks
d.) about 12 weeks
