Was working on it but it disappeared?

Answer 2

Assume there were R original Residents
And C dollars was the original Cost per resident.

R * C = 1.2 x 10^6 ----- (1)
Cost per resident increased by 3. New cost is (C + 3)
225 fewer residents implies (R - 225) is the new number of residents.

(C+3) * (R - 225) = 1.2 x 10^6 ----- (2)

Solve for C. Find R from equation (1) and substitute in equation (2)

The new (or revised) cost to the residents will be: C + 3.

Answer 3

RC = 1200000 ---- (1)
Divide both sides by C
R = 1200000/C
Put that in (2): (C+3)(R-225) = 1200000 ------ (2)
(C+3)(1200000/C - 225) = 1200000
Solve for C
