I'm stuck on this math problem: Jenna is buying concert tickets for her group of five friends. She's able to get two of the tickets from the concert website for $50 each before they sell out. A scalper offers to sell her two more tickets for 240% of the normal price, but Jenna convinces him to give her $10 off that total payment. Finally, one of her friends gets a discounted ticket through her job for 60% of the normal price. How much do Jenna's friends pay for their tickets in total?
Can you help?
