$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.
