. A teacher used a lever in physics class to lift a 52 pound object with only 16 pounds of force. If the weight lifted in pounds, y, varies directly with the force applied to the lever in pounds, x, then how many pounds will the lever lift if 28 pounds of force is used?

Answer:

  91 lbs

Step-by-step explanation:

28/16 = 1.75 times as much force will lift 1.75 times as much weight:

  1.75 × 52 lbs = 91 lbs

The lever will lift 91 pounds if 28 pounds of force are used.
