Answer:
31*3 which= 93 lbs
Step-by-step explanation:
One way to solve this question is to realize that every 100 pounds on planet A equals only 3 pounds on planet B.
So, 3100 pounds(the weight of the elephant on Planet A) divided by 100 = 31. Then that number times 3 will give you the weigh on planet B which is 93 pounds.
3100/100=31
31*3= 93 lbs (weight of the elephant on planet b)
or (3*3100)/100 which = 93 lbs as well
Hope that helps
