An elephant eats about 500 pounds of grass and leaves every day. there are 2 african elephants and 3 asian elephants living in the city zoo. how many pounds of grass and leaves do the zookeepers need to order each week to feed all of the elephants? 3,000 pounds 17,500 pounds 2,500 pounds 21,000 pounds

Lets think about this for a moment
500lb per 2 african and 3 asian elepahnts so 500 * 5 > 2500LB
That is 1 day but 7 days are in a week so this is what we need > simple > 2500 * 7 = 17,500lbs a week.

Hi , the answer is 2500 because 2+3=5 and 500 times 5 equals your answer which is 2500 , per day they eat that , per week it would be 17,500

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
