The weight of an object on Venus is approximately
its weight on Earth. If an object weighs 100 pounds on Earth, then the object’s weight on Venus is given by
(100)=90 pounds. The same object’s weight on Jupiter is approximately
of its weight on Earth; therefore, the object weighs
(100)=230 pounds on Jupiter. The difference between the object’s weight on Jupiter and the object’s weight on Venus is
230−90=140 pounds. Therefore, an object that weighs 100 pounds on Earth weighs
140 more pounds on Jupiter than it weighs on Venus.
Choice A is incorrect because it is the weight, in pounds, of the object on Venus. Choice B isincorrect because it is the weight, in pounds, of an object on Earth if it weighs
100 pounds onVenus. Choice D is incorrect because it is the weight, in pounds, of the object on Jupiter.
