Answer provided by our tutors
let
s = the cost per student
t = the cost per teacher
the 1st group has 25 students and 2 teachers and cost $97.50
25s + 2t = 97.50
the 2nd group had 32 students and 3 teachers and cost $127
32s + 3t = 127
by solving the system of equations
25s + 2t = 97.50
32s + 3t = 127
we find
s = $3.5
t = $5
