Sandra saves 9% of her salary for retirement this year salary was 1000 more than in her previous year and she saved $4050 what was your salary in the previous year

$44,000

Step-by-step explanation:

The statement indicates that Sandra saves 9% of her salary and she saved $4,050 this year. That means that the 9% of her salary, x, is equal to $4,050. You can write the following:

x*0.09= 4,050

Now, you can isolate x to find her salary this year:

x=4,050/0.09= 45,000

Then, you have that this year salary was 1000 more than in her previous year. As you have found her salary for this year, you can subtract 1,000 from it to find her salary in the previous year:

45,000-1,000= 44,000

According to this, the answer is that her salary in the previous year was $44,000.
