tickets for the harlem globetrotters
show at michigan state university in
2010 cost $16, $23, or, for vip seats, $40.
total revenue = 16x + 23y + 40z
if 9 times as many $16 tickets were sold
as vip tickets,
x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold
as vip tickets,
x = 9z => x – 9z = 0, sales of all three kinds of tickets would
total $46,575.
16x + 23y + 40z = 46575, how many of each kind of ticket would
have been sold?
solve for x, y and z
x − 9z = 0
x − y − z = 55
16x + 23y + 40z = 46575
x = 1170
y = 985
z = 130
