Question: Bess and Holly are playing Frisbee at the park. Bess can throw the Frisbee as far as 20 meters and she does this 4 times. Holly can only throw the Frisbee as far as 8 meters and she does this 5 times. Each time Bess throws a Frisbee, she throws it back to her original position. Holly leaves her Frisbee where it lands every time she throws it. In total, how many meters have the thrown Frisbees traveled?
Answer: Bess throws the Frisbee out 4 times * 20 meters each time = 80 meters. She then throws it back which doubles the distance traveled to 80 meters * 2 = 160 meters. Holly throws the Frisbee out 5 times * 8 meters = 40 meters. So in total, Holly and Bess have thrown the Frisbees 160 + 40 = 200 meters. The answer is 200.

Q: There is three less than four times the number of students in Elementary School as there are in Middle School. If the number of students in Middle school is 50, calculate the total number of students in both levels.
A:
The number of students in elementary school is three less than four times the number in middle school: 4 * 50 students = 200 students. This means that there are 200 students - 3 students = 197 students in Elementary school. The total number of students in both levels is 197 students + 50 students = 247 students. The answer is 247.
