$466

Step-by-step explanation:

Represent her salary by s.  Then the amount spent on rent is s/2.

After spending 168 on her electric and water bills, she had s/2 - 168 dollars left.  She spent half of this on her phone bill, leaving her with

s/2 - 168

dollars.  

       2

After buying $57 worth of gas, she had

s/2 - 168

- 57 dollars left, and this came to $92.  

       2

We must now solve for s.

First, multiply all three terms by 2.  We get

s/2 - 168 - 2(57) = 2(92), or

s/2 - 168 - 114 = 184

Simplifying this, we get s/2 = 168 + 114 + 184, or s/2 = 466.

She spent half her salary (that is, half of s) on rent.  As seen above, this is $466.
