The total cost of a school camp for Year 10 students was $21 280.
Each teacher paid $185 to attend and each student paid $165.
There was one teacher for every 15 students.
Find the number of teachers and students that attended the camp.
:
let t = no. of teachers
There was one teacher for every 15 students, therefore
15t = no. of students
:
185t + 165(15t) = 21280
185t + 2475t = 21280
2660t = 21280
t = 21280/2660
t = 8 teachers
then
8 * 15 = 120 student

Check this on your calc,enter
(185*8) + 165(120) =
