Final answer:
To find the percentage of students who passed the final exam in Mr. Jones' math class, divide the number of students who passed by the total number of students in the class and multiply by 100.
Step-by-step explanation:
To find the percentage of students who passed the final exam in Mr. Jones' math class, divide the number of students who passed by the total number of students in the class and multiply by 100. In this case, 34 students passed and there are 40 students in total. So, the percentage of students who passed is:
(34 / 40) x 100 = 85%
Therefore, 85% of the students in Mr. Jones' math class passed the final exam.
