Sandra saves 14% of her salary for retirement. This year her salary was $2,000 more than in the previous year, and she saved $7,
Brums [2.3K]

Answer: Sandra's salary in the previous year was $48,000

Step-by-step explanation:

Hi, the expression given is missing the $2000 more that she earns this year.

0.14 (x +2000) =7000

Where:

  • <em>x is Sandra's salary in the previous year. </em>
  • <em>0.14 is the decimal form of 14% (14/100=0.14) </em>

Solving for x :

0.14(x) +0.14 (2000) =7000

0.14x +280 =7000

0.14 x = 7000-280

0.14x = 6720

x = 6720/0.14

x=48,000

Sandra's salary in the previous year was $48,000

Feel free to ask for more if needed or if you did not understand something.
