3.) Freda and her crew begin a voyage to the island of Fiji with 145lbs of food.  The crew plans to eat a total of 15 pounds of food per day.  The crew plans to have 25lbs of food remaining when they end their voyage.  What is the equation?

• y = 145x - 15

• y = -15x + 145

  which can also be written as y = 145 - 15x

• y = 15x - 145
