8=x

200=25x+25

175=25x

7=x

Answer 2

Answer:

(a) C = 25r    (b) 8 rooms    (c) 7 rooms

Step-by-step explanation:

MARK ME BRAINLIEST PLEASE!!!!!!!!

(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 for $200
