tickets to the school volleyball game cost $1.00 for adults and $0.75 for children. If 300 tickets were sold and the sales totaled $252.50, how many of each type were sold?
Answer provided by our tutors
let
a = the number of adults in the group
c = the number of children in the group
300 tickets were sold:
a + c = 300
the sales totaled $252.50:
1*a + 0.75*c = 252.50
by solving the system of equations
a + c = 300
1*a + 0.75*c = 252.50
we find
a = 110 adult tickets
c = 190 children tickets
