Mr. John works at a shopping mall and receives a monthly income of $2000, but he spends approximately 5% of this amount on public transport to and from the mall in a month. How much will he have left after deducting his monthly transport fare from his income? Let's think first. Chain of thought:
5% of $2000 is (5 / 100) * $2000 = $100. After removing his transport fare, he will have $2000 - $100 = $1900 left.
Therefore, the answer is 1900.
