Question

After spending 30% of her salary Sara was able to deposit $120 in the bank. What is her salary?

Answer 1

Answer: $400

Explanation:

So first you set it up in a equation. You put the amount she put in the bank over x (the x represents her full salary) which equals the percent she already spent over her full salary. That would be 120/x=30/100 you would then cross-multiply to get 12,000 = 30x. you then divide 30 from both sides to get x =400.
