Final answer:
There are 31 students from Mr. Ott's class going on the field trip. We determined this by setting up an equation based on the information given that Ms. Cho's class and Mrs. Wye's class combined have 6 more students than Mr. Ott's class and the total number of students going on the trip from all three classes is 68.
Step-by-step explanation:
Let the number of students in Mr. Ott's class be x. According to the problem, Ms. Cho's class and Mrs. Wye's class combined have x + 6 students. We know that together, all three classes have 68 students going on the field trip. To find out how many students are from Mr. Ott's class, we can set up the following equation:
x + (x + 6) = 68
Merging the two x terms gives us:
2x + 6 = 68
Subtract 6 from both sides to get:
2x = 62
Divide both sides by 2 to find the value of x:
x = 31
So there are 31 students from Mr. Ott's class going on the field trip.
