Acar 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?

Total Commission = $400

Step-by-step explanation:

Since total is $9000 (in sales) -- commision is 4% on the first $8000 and 8% in the additional part over $8000 (9000-8000=1000). So 8% on $1000.

Total commission = 4% of 8000 + 8% of 1000

= (0.04)(8000) + (0.08)(1000)

= 400

Total Commission is $400
