A car dealership pays you 4% commission on your first $8,000 in car sales and 8% commission on additional sales over the $8,000. If you made $9,000 in car sales, how much is your commission?

If this was your first car sale, you would get $320 from the four percent (if you are only getting 4% on the 8grand), and an additional $720 from the 8% making a total 1040

However, if you are getting 4% on the total sales, (which i think you aren't) you would get $360, making the total of of commision $1080
