Answer: MARK ME BRAINLIEST PLEASE!!!!!!!!
(a) C = 25r    (b) 8 rooms     (c) 7 rooms
Step-by-step explanation:
(a) C=25r
(b) C = 25r
  200 = 25r,
  200/25 = 25r/25
  200/25 = 8
  8 = r, therefore 8 rooms can be cleaned for $200
(c) 200-25 = 25r
  200-25=175, so 175 = 25r, then divide both sides by 25, and you get
  7 = r , so therefore 7 rooms can be cleaned
