Answer:

x = 25.

Step-by-step explanation:

Original cost per person:: 2000/x

Changed cost per person:: 2000/(x-5)

---------------------------

Equation:: changed - original = 20

2000/(x-5) - 2000/x = 20

2000x - 2000x + 2000*5 = 20x(x-5)

10000 = 20x^2-100

 

----

500 = x^2 - 5x

------------------

x^2 - 5x - 500 = 0

(x+20)*(x-25) = 0

-----

Only positive root makes sense ====> x = 25.
