Question

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?

Answer 1

`\$40000`

Explanation:

Let's start by finding Sandra's salary this year.

We are given that she saved $3,360 or 8% of her total salary this year.

Let's represent her total salary this year as "x" and set up an equation:

`\$3360=8\%x\\`

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

`$3360=(8)/(100)x`

Multiply 100 to both sides:

`336000=8x`

Divide both sides by 8

`x=42000`

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:

`42000-2000=40000`
