Question 278429
At a university, 1200 students are enrolled in engineering. There are twice as many in electrical engineering (e) as in mechanical engineering, and three times as many in chemical engineering (c) as in mechanical engineering (m). 
QUESTIONS: 
1. Which system of eqations represents the number of students in each program?
A)c+m+e=1200,2m=e,3m=c
B)c+m+e=1200,3m=e,2m=c
C)c+m+e=1200,2e=m,3c=m
D)c+m+e=1200,2m=e,3m=2e
-------------------------
There are twice as many in electrical engineering (e) as in mechanical engineering --> e = 2m
------------------------
and three times as many in chemical engineering (c) as in mechanical engineering (m) --> c = 3m
-----------------------------
-----------------------------
2. How many students are enrolled in the mechanical engineering program?
A)200
B)400
C)600
D)1200
----------
c+m+e = 1200
3m + m + 2m = 1200
6m = 1200
