10.) A salesman has a basic salary of P4,500 and a commission of 5% on all sales above P50,000. What were his total sales in a month when he earned P13,177.50?

Solution: The salesman’s commission is 13,177.50 – 4500.00 = 8677.50.
The amount which is 8677.50 is 5% of his commission above 50,000.00
To know his actual sale, we multiply the 5% amount to 20 to make it 100%.
That is, 8677.50 x 20 = 173 550.00. This is above 50,000, so we still have to add 50 000.00.
Therefore, the total sales is 173 550.00 + 50 000.00 = 223 550.00

Answer: Php223 550.00
