Answer:
Step-by-step explanation:
The cost that a carpet can cleaning company charges is directly proportional to the number of rooms cleaned. The cost to clean 50 rooms is $1,100.
A.) Write a direct variation equation to represent the cost.
Cost ∝ Number of room
C ∝ N
C = kN
k = Constant of Proportionality
k = C/N
k = 1100/50
k = 220
B.) Using the equation found in part a, how much would it cost a hotel to have 150 rooms cleaned
c = 220 × 150
c = $33000
Cost to clean 150 rooms = $33,000
