Sandra saves 12% of her salary for retirement. this year her salary was $3,000 more than in the previous year, and she saved $4,200. what was her salary in the previous year?

So since we know she saved 12% in the previous year so you would make a graph and then draw 100 squares now since 12 dosen't go into 100 evenly you would multiply 12 until you get 96% (which is multiplying 12 by 8) then her salary would be $4,200 dollars multiplied by 8 which is 33,600 dollars then to get your 4 more percent you would divide 12 by 3 which is 4 and you would also divide 4,200 by 3 which is 1,400 and add that to 33,600 dollars and her salary would be 35,000 dollars in the previous year her current year salary would be 38,000 dollars.
