Question 960742
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.
