A machine is used to fill each of several bags with 16 ounces of coffee. After the bags are filled, another machine weighs them. If the bag weighs 0.5 ounces more or less than the desired weight, the bag is rejected. Which of the following equations could be used to find the heaviest and lightest bag the machine will approve? (Let x represent the acceptable weights of a bag of coffee.)

• |x - 16| = -0.5

• |x + 16| = 0.5

• |x - 0.5| = 16

• |x - 16| = 0.5
