Brandon and Jacob buy used cars at the same time. Brandon buys a car with 10,000 miles on it. He drives an average of 100 miles a week. The equation that follows can be used to determine how many miles, m, will be on the car after any number of weeks of driving, w:
m = 100w + 10,000
So every week you would add 100 miles right? In that case it would take 20 weeks?
