Question 1009178: Larry saves 15% of his annual salary for retirement. This year his salary was
$2,000 more than last year, and he saved $3,300. What was his salary last year?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! x = last year's salary.
x + 2000 = this year's salary.
.15 * (x + 2000) = 3300
simplify to get:
.15 * x + .15 * 2000 = 3300
simplify further to get:
.15 * x + 300 = 3300
subtract 300 from both sides of the equation to get:
.15 * x = 3000
divide both sides of the equation by .15 to get:
x = 20,000
his salary lastyear was 20,000 ***** that's your solution.
his salary this year is 22,000
.15 * 22,000 = 3,300.
solutionis confirmed as good.
