A salesman is paid a monthly salary of

sh6000 and a commission of 5% for sales
above sh 50 000. In a certain month, the
salesman's total earnings were sh15000.
What was the total sales for the month?

5% = 5 / 100 = 0.05

6 000 + 5% ( x - 50 000 ) = 15 000

6 000 + 0.05 ( x - 50 000 ) = 15 000

6 000 + 0.05 x - 0.05 • 50 000 = 15 000

6 000 + 0.05 x - 2 500 = 15 000

3 500 + 0.05 x = 15 000

Subtract 3 500 to both sides

0.05 x = 11 500

x = 11 500 / 0.05

x = 230 000

He had total sales of 230 000.
