Hello!
Her first commision would have to be multiplied by 5% first, which would be 6,000 x .05
This would equal to $300.
The second part would be .075 x 6000.
This equals to $450
Then, .01 x 12,000
This equals to $120.
Add all commisions, 300+450+120
****$870 is the total commision she received. ****
I hope I did this right. It's my first time on brainly. Tell me if you got it. Sorry if I didn't help
