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
[tex]w+831\leq 1250[/tex]
[tex]w+831-831=1250-831[/tex]
Using subtraction property of inequality
[tex]w\leq 419[/tex]
Hence, the elephant can carry amount of additional weight 419 pound or less than 419 pounds.
Therefore, option C is true.
