(b) How many rooms can a hotel pay the company to clean for $200? Write and solve an equation. Show your work!
(c) Suppose the hotel plans to tip the carpet cleaners $25. In that case, how many rooms can the hotel get cleaned for $200? Write and solve an equation. Show your work!

Answer 1

a) Y=25x because each room costs $25

b) 200=25x =8 rooms divide 200 by 25 and you get 8 because each room costs 25$

c)200=25x+25

Answer 2

a) Y=25x because each room costs $25
