For the hiking portion of your trip, you and your friends carry the same amount of
equipment, which works out to 35 pounds of equipment each. For extra money, you can
hire an assistant, who will carry 50 pounds of equipment. Each assistant charges a flat
fee of $50 and an additional $22 for each mile. The total amount you would have to pay
1 assistant is $512. How many miles will your group be hiking?
