Pani-rosa [81]

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

$10,000\dfrac{4}{100}=400$

Sales over 10,000 is

$38,000-10,000=28,000$

10% commission on all sales over 10,000 is

$28,000\times \dfrac{10}{100}=2,800$

Now, the total commission is

$400+2,800=3,200$

Therefore, the total commission is 3,200.
