How many years will it take the schools to have the same enrollment? (break even point)

Set up two equations:

Sunshine College has 1100 students and gains 45 per year:

This can be written as 1100 + 45x ( where x is the number of years.)

Marigold has 2000 students and loses 15 per year.

This is written as 2000 - 15x ( where x is the number of years.)

Now set the two equations to equal each other and solve for x:

1100 + 45x = 2000 - 15x

Subtract 1100 from each side:

45x = 900 - 15x

Add 15 x to each side:

60x = 900

Divide each side by 60:

x = 900 / 60

x = 15

It will take 15 years.

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
