Algebra help needed A.S.A.P. (Please)?

Question

Ok, I need help understanding what a Mathmatical Verbal Model is (in simple terminology please) and how to to apply and interpret it to the following problem...

THE FACTS=
*In 1990, enrollment at East Valley H.S. was 840. From 1990 to 1996 emrollment increased an average rate of 24 students per year. East Vally was built to hold 900 students*

THE PROBLEM=
I need to find the possible # of years since 1990 when the schools enrollment was no greater that the "Maximum Capacity" for which the school was built.

I know the answer is 2 YEARS. Now how i INCORPURATE the answer into a Verbal Model label and then interpret it???


Anyone's help would be greatly appriciated and I will be a wiser more productive student because of your help. HaHa Just added a little sence of humor to boring 9th Grade ALGERBRA.

Thanks in advance for your help.

Answer 1

It may be boring, but if I do it for you it won't help you at all.
Do it, it is easy. The school has 24 new enrollments each year but how many leave? or is the net increase 24 per year.
