# Each student in Ms. Grinkov's class is either a junior or a senior. Ms. Grinkov has 30 seniors and 35 juniors in her class. Recently, she took some students from her class on a field trip. Of the 30 seniors in the class, 4/5 went on the trip.
Use this information to answer the questions below.
If not enough information is given to answer a question, reply "Not enough information."
(a) How many students are in the class?
(b) How many students from the class did not go on the field trip?
(c) How many seniors from the class went on the field trip?

Accepted Solution

A:

(a) The total number of students in Ms. Grinkov's class is:
30 (number of seniors) + 35 (number of juniors) = 65 students.
(b) The number of seniors who did not go on the field trip is:
30 (total seniors) - (4/5)(30) = 6 seniors who did not go on the trip.
The number of juniors who did not go on the trip is not given, so we cannot determine the total number of students who did not go on the field trip.
(c) The number of seniors who went on the field trip is:
(4/5)(30) = 24 seniors who went on the trip.
