Q4: Now you are managing the sales target of the company. Assuming every property our team sell is $10,000,000, and the after-tax commission we receive is 5% of the property price. The developer will pay the commission in 12 monthly installments. Now you know that the sales target for commission received for NEW properties sold in the next month will be $1,000,000. What is the closest number of new properties we need to sell in order to hit the target of receiving $1,000,000 commission based on the 12-month installment paid by the developers? 10 15 20 25 30
