Lizzy: Rafael works 10 hours on Monday and 8 hours on Tuesday on his delivery job. With 20 hours left to work in the week, how much money does Rafael make if he is paid $20 per hour?.
Me: Hmmm, let me think. I think this is the detailed solution:
The total number of hours that Rafael has worked by Tuesday is 8 + 10 = 18 hours. To complete his assigned work hours, Rafael works 20 hours more, making his total weekly hours to be 18 + 20 = 38 hours. Since he is paid $20 per hour, he makes $20 * 38 = $760 a week. Final answer: 760.
