You can put this solution on YOUR website!
Let the income before taxes = x
The income after taxes will then be x+-+.1%2A%28x+-+3000%29
The problem says the income after taxes is 12000, so
x+-+.1%28x+-+3000%29+=+12000
x+-+.1x+%2B+300+=+12000
.9x+=+12000+-+300
.9x+=+11700
x+=+13000
The income before taxes was $13,000
