The Rocking Pebbles At concerts given by the group The Rocking Pebbles, some of the tickets are sold for reserved seats, and the rest are general admission. For a recent series of two weekend concerts, the Pebbles pledged to give their favorite charity an amount equal to half of what was paid for general-admission tickets. After the concerts, the charity called the Pebbles’ manager to find out how much money the charity would be getting. The manager looked up the records. She found that for the first night, 230 reserved-seat tickets and 835 general admission tickets were sold. For the second night, 250 reserved-seat tickets and 980 general admission tickets were sold. The manager saw that the total amount of money collected for the tickets was $23,600 for the first night and $27,100 for the second night, but she didn’t know the prices for the two different kind of tickets. (The ticket prices were the same at both concerts.) Figure out what the two ticket prices were, and use that information to tell the manager how much the Pebbles will give to the charity.
