A:
Answer:  in 12 years (2017)                23,000 students enrolledStep-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 + 750xCollege B: y = 35,000 - 1000xSolve the system using the Substitution Method:14,000 + 750x = 35,000 - 1000x            +1000x               +1000x14,000  + 1750x = 35,000-14,000                 -14,000                 1750x = 21,000                         x = 12Input 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
