Chris is planning to take a week long vacation next summer. Unfortunately Chris's job does not offer vacation pay so they will have to give up $750 in earnings to take the vaction. Chris is trying to decide between a trip to the Lake of the Ozarks and a trip to Chicago. The trips financially cost about the same, but if Chris goes to the Lake they will get to waterski and to hang out with a high school friend they haven't seen for a couple of years.
