You divide 3 from both sides
and the answer is a=3
because 3 divided by 3 is 0
and you don't have to write it
and then 9 divided by 3 is 3
so replace the 9 with 3 and it gives you
a=3

Step-by-step explanation:
sorry if this doesn't work. i'm not 100% sure but its worth a try.

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
