Answer:
$1072
Explanation:
To answer the question, we have to follow backwards as if it is a story.
1) She is left with $82 and pays $52 on gas so together that makes $134
2) $134 is one half of what was left on her phone bill so $134 and $134 together makes 268
3) $268 was spent on her electric, this plus the $268 left previously makes $536
4) This is one half of her salary so we now double this, $1072!
Hope this helps, have a lovely day! :)
