Step-by-step reasoning process: Dino works 20 hours at a rate of $10 an hour, which means that work pays him 20 * 10 = 200 dollars a month. Dino works 30 hours at a rate of $20 an hour, which means that work pays him 30 * 20 = 600 dollars a month. Dino works 5 hours at a rate of $40 an hour, which means that work pays him 5 * 40 = 200 dollars a month. Altogether, this means Dino makes 200 + 200 + 600 = 1000 dollars a month. You subtract Dino's expenses of 500 from this amount, meaning he has 1000 - 500 = 500 dollars at the end of the month.
[Q & A] The question is Dino does some online gig work for a living. He works 20 hours a month making $10 an hour. He works 30 hours a month making $20 an hour. He works 5 hours a month making $40 an hour. He pays $500 a month in expenses. How much money does Dino have left at the end of the month?
