Answer provided by our tutors
let
a = the number of adult tickets bought
s = the number of student tickets bought
she bought 4 more student tickets than adult tickets
s = a + 4
Mimi had $174 to buy tickets to a concert
10.50a + 7.50s = 174
by solving the system of equations
s = a + 4
10.50a + 7.50s = 174
we find
s = 12 tickets
