Tickets to a concert cost $9.00 for adults and $6.00 for students. A total of 950 people paid $7 500 to attend. How many students attended the concert?
2 answers
350 students
9 a +6 s = 7 500 surely a typo
a = 950 - s
so
9 (950-s) + 6 s = 7500
8550 - 9 s + 6 s = 7500
-3 s = -1050
s = 1050/3 = 350
a = 950 - s
so
9 (950-s) + 6 s = 7500
8550 - 9 s + 6 s = 7500
-3 s = -1050
s = 1050/3 = 350
