A high school has 900 students, 40% of whom are drama majors. A second high school has a 75% drama majors population. The school board plans to merge the two schools into a Performing Arts magnet school that will then have a 52.5% drama majors student body. How many students are at the second school?

Let x = # students at second h.s.
=======================
0.4(900) + 0.75x = 0.525(900+x)
solve for x.

Solution A is 30% acid and solution B is 60% acid. How many gallons of each solution must be used to create a 60 gallon mixute that is 50% acid. I have to set this up as a system of equations, and I thought one system was x + y = 60, but I can't get an answer, please help

If you piggy back one question on another you are unlikely to get an answer, because it looks as though the question has been answered. You should show you question as a new problem.

0.4(900)+0.75x = 0.525(900+x)
360 + 0.75x = 472.5 + 0.525x
0.75x - 0.525x = 472.5 - 360
0.225x = 112.5
0.225x/0.225 = 112.5/0.225
x = 500
