Why arguments passed in SASS functions have dollar sign in front of them? E.g. $target, $context..

Does this mean we have to declare $target and $context as variables beforehand?

and also, must we specifically write $target and $context?

can we use other words like say, $number and $width?

Something like that:

@function px-to-pc ($number, $width:1000px) {
 @return  ($number / $width) * 100%;
}

The $ dollar sign is used to declare variables in Sass.

We must use the $ dollar sign to let Sass know the parameter is a variable and not a string, integer, boolean etc.

The dollar signs are just the Sass syntax, like how you use them for Sass variables in general, ie:

$primary-color: #FFDA6A;
$secondary-color: #548DFF;
// etc.

Just like variable names, you can name the arguments passed into functions/mixins anything you like, so your example would work just fine.
