Answer 1

There are 121 students in 9th grade and 115 students in 10th grade at Jefferson High School.

Step-by-step explanation:

This question involves counting and analyzing data about grade levels and handedness of students at Jefferson High School. To answer the question, we need to use the given information:

- There are 236 students in 9th and 10th grades combined.

- Out of these, 121 students are in 9th grade.

- Among the 214 right-handed students, 103 are in 10th grade.

We can use these numbers to find out how many students are in each grade level.

Let's denote the number of 9th-grade students as 'x' and 10th-grade students as 'y'.

From the given information:

x + y = 236 (total number of students)

x = 121 (number of 9th-grade students)

y = 103 (number of 10th-grade students)

To find the value of 'y', we can substitute the given value of 'x' into the first equation:

121 + y = 236

y = 236 - 121

y = 115

Therefore, there are 121 students in 9th grade and 115 students in 10th grade.
