Sandra saves 8% of her salary for retirement. This year her salary was $2,000 more than in the previous year, and she saved $3,360. What was her salary in the previous year?

Step-by-step explanation:

Note that any percentage is equivalent to that number over 100.

Multiply 100 to both sides:

Divide both sides by 8

The question states "this year her salary was $2000 more than in the previous year".

This means that her salary in the previous year is equivalent to:

the answer is (-4,-4)
