Answer:
The commission would be 1560
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
