A group of students are meeting in the cafeteria. 70 students have already arrived. This is 35% of the group. How many students are in the group?

Responses
A 255
B 2450
C 4550
D 200
E 500

To find the total number of students in the group, we can set up a proportion:

70 is to 35% as X is to 100%

(70 / X) = (35 / 100)

Cross-multiplying gives us:

35X = 7000

Dividing by 35 on both sides:

X = 200

Therefore, there are 200 students in the group. Answer choice D is correct.
