Question 960742: Janice gets 37,500 monthly income from her boarding house for teachers and students. The teachers pay 2,000 each per month and they compose 75percent of the boarders. If the total rent from all the teachers is 80percent of the boarding house's monthly income, how much is the rent of each student?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! monthly income is 37,500
teachers pay 80% of that.
teachers pay .80 * 37,500 = 30,000
each teacher pays 2,000, so number of teachers has to be 30,000 / 2,000 = 15.
teachers are 75% of the boarders, so boarders are 15/.75 = 20.
must be 5 students.
they pay 37,500 - 30,000 = 7,500.
they each pay 7,500 / 5 = 1,500.
