A company offers a raffle whose grand prize is a $35,000 new car. Additional prizes are a $900 television and a $600 computer. Tickets cost $18 each. Ticket income over the cost of the prizes will be donated to charity. Use the method of Example 9.8.5 to answer the following question. If 3,000 tickets are sold, what is the expected gain or loss (in dollars) of each ticket?

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
