Let T denotes temperature (in degrees Celsius) of a camel throughout the day.
Now it is given that the normal temperature of camel is ${37}^{\circ }C$ and it can vary from by up to ${3}^{\circ }C$. Thus, the required absolute value inequality is:
$|T-37|\le 3$
Now consider,
$|T-37|\le 3$
$-3\le T-37\le 3$
$-3+37\le T-37+37\le 3+37$
$34\le T\le 40$
The solution is $34\le T\le 40$.
