4percent commission on the first 6,000 7 percent on the next 6,000 and 12 percent on sales over 12,000 last month they sold 19,500 what was his total

The commission would be 1560

Step-by-step explanation:

In order to find the commission, you need to multiply out each of the 3 commissions separately. Start by calculating out the first 6,000

6,000 * 4% = 240

Now, for the next 6,000

6,000 * 7% = 420

And lastly, we need to calculate out how much to make on the last 7,500

7,500 * 12% = 900

And to get the final answer, add all of the commissions together.

240 + 420 + 900 = 1560
