Question 914548: Hi! Kindly help me. I just don't know how to get through with it. Here's the problem:
A development project which was financed by ecological organizations amounted to PHP3.6 million. If there had been two more contributors and the expenses were shared equally, it would have cost each organization PHP 300,000 less. How many organizations contributed to the project?

N number of Original Contributors

3.6(N+2) - 3.6N = .3N(N+2)
.3N^2 + .6n -7.2 = 0
3N2 + 6N - 72 = 0
N^2 + 2N - 24 = 0
(N+6)(N-4) = 0, N = 4, Or1ginally
