Question

Yara just received a 6% raise in salary of 3,120 per year how much per year was she earning before the raise

Answer 1

She would've recieved 52,000 (Fairly certain thats right)

Answer 2

before the raise, Yara was making "x", which is 100% of her salary,
now, later on she got a 6% of that "x" in increased salary, and she's
making 3,120, so 100% + 6% added, is 3,120
thus
`\bf \begin{array}{ccllll} amount&\%\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ x&100\\ 3,120&100+6 \end{array}\implies \cfrac{x}{3,120}=\cfrac{100}{100+6}`

solve for "x"
