1000 pounds

 B.

100 pounds

 C.

400 pounds

 D.

1200 pounds

Answer 1

I'm pretty sure the answer is C. 400 pounds.

Answer 2

Answer:

C:400 pounds

Step-by-step explanation:

Let w be the amount of additional  weight which can carry by an elephant.

The elephant can carry weight  on its back=1250 pounds

The combined weight of four people=831 pounds

We have to find the value of w.

According to question

$w+831\leq 1250$

$w+831-831=1250-831$

Using subtraction property of inequality

$w\leq 419$

Hence, the elephant can carry amount of  additional weight 419 pound or less than 419 pounds.

Therefore, option C is true.
