in 12 years (2017)
23,000 students enrolled
Step-by-step explanation:
Let x represent the number of years since 2005.
Let y represent the number of students enrolled.
College A: y = 14,000 + 750x
College B: y = 35,000 - 1000x
Solve the system using the Substitution Method:
14,000 + 750x = 35,000 - 1000x
+1000x +1000x
14,000 + 1750x = 35,000
-14,000 -14,000
1750x = 21,000
x = 12
Input x = 12 into one of the equations to solve for y.
y = 35,000 - 1000x
= 35,000 - 1000(12)
= 35,000 - 12,000
= 23,000
