Answer provided by our tutors
let
c = the number of children that went to the concert
a = the number of adults that went to the concert
105 people attended the concert
a + c = 105
total receipts for the concert were $228
2.50a + 1.75c = 228
by solving the system of equation
a + c = 105
2.50a + 1.75c = 228
we find
a = 59 adults
c = 46 children
