James is participating in a 5-mile walk to raise money for a charity. he has received $200 in fixed pledgesand raises $20 extra for every mile he walks. use a point-slope equation to find the amount he will raise ifhe completes the walk.

Jamie is hiking up a small mountain. he climbs up at a constant rate of 300 feet/hour until he reaches the peak at 1,500 feet. after that, he hikes down at the same rate to the base of the mountain. the equation that models jamie’s elevation, e, after t hours is e = . jamie’s elevation will be 600 feet after hours and after hours.
