# Santa Claus is assigning elves to work an eight-hour shift making toy trucks. Apprentice earn five candy canes per hour but can only make four trucks an hour. Senior elves can make six trucks an hour and are paid eight candy canes per hour. There's only room for nine elves in the truck shop. Due to a candy-makers' strike, Santa Claus can only pay a total of 480 candy canes for the whole 8-hour shift. (a) How many senior elves and how many apprentice elves should work this shift to maximize the number of trucks that get made? (b) How many trucks will be made? (c) Just before the shift begins, the apprentice elves demand a wage increase; they insist on being paid seven candy canes an hour. In order to give the apprentice elves the raise, Santa cuts back the amount of elves he could have in the truck shop to 8 elves. Now how many senior elves and how many apprentice elves should Santa assign to this shift?
