Question

A school community had planned to reduce the number of grade 9 students per classroom by constructing additional class rooms. However, they constructed 4 less rooms than they planned. as the result, the number of students per class was 10 more they planned. if there are 1200 grade 9 students in the school, determine the current number of class rooms and the number of students per class.​

Answer 1

Step-by-step explanation:

They planned to build n+4 rooms, but built only n

1200/n = 1200/(n+4) + 10

Without even doing the math, recall that 1200 = 24*50 = 20*60
