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?
Let's think: 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 answer is: 23.

Terese thinks that running various distances throughout the week can make one healthy. On Monday, she runs 4.2 miles; Tuesday, 3.8 miles; Wednesday, 3.6 miles; and on Thursday, 4.4 miles. Determine the average distance Terese runs on each of the days she runs.
Let's think: The total distance Terese runs is 4.2 + 3.8 + 4.4 + 3.6 = 16 miles. Therefore, she runs with an average distance of 16 / 4 = 4 miles.. The answer is: 4.

In a section of the forest, there are 100 weasels and 50 rabbits. Three foxes invade this region and hunt the rodents. Each fox catches an average of 4 weasels and 2 rabbits per week. How many rabbits and weasels will be left after 3 weeks?
Let's think: 3 foxes catch 4 weasels each every week for a total of 3 * 4 = 12 weasels. 12 weasels are caught every week for 3 weeks for a total of 12 * 3 = 36 weasels. 3 foxes catch 2 rabbits each every week for a total of 3 * 2 = 6 rabbits. 6 rabbits are caught every week for 3 weeks for a total of 6 * 3 = 18 rabbits. There were originally 100 weasels so now there are 100 - 36 = 64 weasels left. There were originally 50 rabbits so now there are 50 - 18 = 32 rabbits left. There are 64 + 32 = 96 weasels and rabbits left.. The answer is: 96.

Fernanda purchased six audiobooks from Audible to listen to from her audible app. If each audiobook was 30 hours long and she listened to 2 hours of an audiobook each day, calculate the total time it took her to finish the six audiobooks?
Let's think:
To finish an audiobook 30 hours long, listening to 2 hours of each audiobook a day, Fernanda took 30 hours / 2 hours / day = 15 days to finish one audiobook. If she purchased 6 audiobooks, the total number of days she will take to finish all the audiobooks is 6 audiobooks * 15 days / audiobook = 90 days.. The answer is: 90.
