Question

Income tax for some states is computed by taking 3% of the excess income over $3,000 plus 1% of the first $3,000. How much tax is charged on a income of $12,000?

12,000

1 percent on first 3000

3 percent of (12,000 - 3000)

I'm trying to figure the relationship between income tax and chemistry.

there is no relationship it's algebra my bad..

Its ok. I was just grinning to myself. We answer questions no matter the title.
