Two groups recently contacted Cody about employing his services. Unfortunately, both groups will be arriving at the Miami airport this coming Tuesday, and one group wants to book a one-way trip to the Upper Keys while the other group wants to book a one-way he}; to the Lower Keys. Cody already has scheduled a trip to the Upper Keys for the morning, so he will only be able to take one of the two groups (note: if he takes the group wishing to go to the Lower Keys, this will make for a long day). Additionally, on this particular Tuesday Cody will not be able to book a group for either return trip (i.e., his bus will be empty on the drive back). Which group should Cody book, and by how much will Cody '3 overall (business + personal) income increase by booking this group
