At a carnival, Raina bought 16 packs of 8 tickets each. She also found 9
more tickets on the ground. How many tickets did Raina have in all?
Raina bought 16 packs of 8 tickets each, so she bought 16 * 8 = <<16*8=128>>128 tickets.
Including the tickets she found on the ground, she had a total of 128 + 9 = <<128+9=137>>137 tickets. Answer: \boxed{137}.
