Given:
Lamont cotton is 4% commission on the first 10,000 of monthly sales and 10% on all sales over 10,000.
Consider his last month sales is 38,000.
To find:
The total commission.
Solution:
4% commission on the first 10,000 of monthly sales is
![10,000\dfrac{4}{100}=400](https://tex.z-dn.net/?f=10%2C000%5Cdfrac%7B4%7D%7B100%7D%3D400)
Sales over 10,000 is
![38,000-10,000=28,000](https://tex.z-dn.net/?f=38%2C000-10%2C000%3D28%2C000)
10% commission on all sales over 10,000 is
![28,000\times \dfrac{10}{100}=2,800](https://tex.z-dn.net/?f=28%2C000%5Ctimes%20%5Cdfrac%7B10%7D%7B100%7D%3D2%2C800)
Now, the total commission is
![400+2,800=3,200](https://tex.z-dn.net/?f=400%2B2%2C800%3D3%2C200)
Therefore, the total commission is 3,200.
