Answer :
Answer:
3 workers
Explanation:
It is given that Clara is opening a room cleaning business on the campus. For Clara, there are 5 potential workers.
The daily wage of for the worker are :
Alex --- [tex]\$ 110[/tex]
Diane -- [tex]\$ 130[/tex]
Cedric -- [tex]\$ 150[/tex]
Peter -- [tex]\$ 170[/tex]
Zekta -- [tex]\$ 190[/tex]
Each of the worker will clean 8 rooms and $ 21 will be charged for each room to be cleaned.
Therefore, the number of the workers required is :
The marginal revenue product for each worker = 21 x 8 = 168
So, Clara will hire only those workers who have daily wage less than $ 168.
Therefore, Clara will hire 3 workers, namely Alex, Diane and Cedric.
