My question is: Carla is taking attendance for her sixth-grade class. She knows that 2 students are in the restroom, and one less than three times that number of students are absent. If there are four rows with six desks each that are all 2/3 full, how many students does Carla teach, including the ones in and out of the classroom? Your thoughts:
First find the number of absent students: 2 students * 3 - 1 = 5 students. Now find the number of students in each row of desks: 6 desks / row * 2 students / 3 desks = 4 students / row. Now find the number of students in all the rows: 4 rows * 4 students / row = 16 students. Now add the students that are absent or in the bathroom: 16 students + 2 students + 5 students = 23 students. The final answer: 23.
