Question 253346
300 students attend a dance.
Band A charges $600 to play for the entire evening.
Band B charges $350 plus $1.25 for each ticket sold
Charges for band B = 350+300*(1.25)
                   = 350+375
                   = 725 $
I will choose band A 
and the the cost per ticket you need to cover the expenses = 600/300 = 2$
