Question. Adam earns $40 daily in his job. 10% of his money is deducted as taxes. How much money will Adam have earned after taxes after 30 days of work?
Answer. 1080
What step-by-step reasoning justifies that answer?
Reasoning: The amount of money deducted from Adam's daily pay is $40 / 10 = $4. So after deducting 10%, Adam’s daily pay is $40 – $4 = $36. This means that in 30 days he earns $36 * 30 = $1080.
