A company makes and boxes spaghetti.

• One machine fills each box with approximately 32 ounces of spaghetti.

• After the boxes are filled, another machine weighs each box.

• A box is discarded if the weight of the box differs by more than 0.25 ounce from the target weight of 32 ounces. Which inequality can be used to find the range of acceptable weights, x, of the spaghetti?

• |x – 0.25| ≤ 32

• |x + 0.25| ≤ 32

• |x – 32| ≤ 0.25

• |x + 32| ≤ 0.25
