Problem
A group has chartered a bus to Atlanta. The driver costs $200, the bus costs $500, and parking in Atlanta will be $90. You have already paid $700 to reserve the bus and a driver. The driver's fee is non-refundable, but the bus may be canceled a week in advance at a charge of $75. At $20 per ticket, at least how many people must buy tickets so that the trip need not be canceled?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
