Question 253346
Assume 300 students attend a dance. Which band would you choose and the cost per ticket you need to cover your expenses.
Band A charges $600 to play for the entire evening
Flat Rate for any number of students: $600
with 300 students the charge will be $600
Cost per ticket to cover expenses would be 600/300 = $2.00 
----------------------------------------------------------
Band B charges $350 plus $1.25 for each ticket sold
Band B charges $(350+1.25x) for "x" students
with 300 students the charge will be 350+1.25*300 = $725
Cost per ticket to cover expenses would be 725/300 = $2.43
