The drama club raised a total of $1,123.50 selling
tickets to its production of Othello. Tickets cost $4.50
for adults and $2.00 for students. Three times as
many student tickets were sold as adult tickets.
Which system of equations can be used to find a, the
number of adult tickets sold, and s, the number of
student tickets sold?
a = The number of adult tickets sold.
s = 3a = the # of student tickets sold.
4.5a + 3a*2.0 = 1123.50.
10.5a = 1123.50,
a = 107.
s = 3a = 3*107 = 321.
