Answer: $560
Explanation:
Mary Robertson sells tires at a service center.The commission rates on tires sold is given as under:
10% commission on the first $ 1000 of sales,
15% commission on the next $2000 of sales and
20% commission on sales more than $ 3000
So, commission is calculated as below:
10% of $ 1000 = 10/100*1000 = 100
15% of $2000 = 15/100*2000 = 300
20% of $800 = 20/100*800 = 160
Total Commission = $100 + $300 + $160 = $ 560
Hope it helps.
Thank you..!!
