Probably multiplication.

Since there are twice as many pounds ( 2 lb to 4 lb ), the amount of jelly beans should also be multiplied by 2.

Not sure if this is what you were looking for, but good luck!

you would need to multiply 550 by 2 because a 2lbs bag contains 550, and you need to find out how many a 4lbs bag contains, and the answer would be 1100 jelly beans, hope this helps
