Mavis L. Wanczyk is no doubt a very happy woman right now — and still in shock — as she was revealed Thursday afternoon to be the owner of a winning Powerball ticket worth $758 million. That’s the highest amount ever won by a single ticket in North America.

At a press conference at the Massachusetts State Lottery Headquarters in Braintree, Wanczyk took questions from the press after learning she’s now worth hundreds of millions of dollars.

Wanczyk bought her ticket at Pride Station & Store on Montgomery Street in Chicopee, the town where she lives.

The Massachusetts State Lottery had mistakenly first said the winning ticket was sold in Watertown. “When manually recording the names of the retailers that sold the jackpot winning ticket and the $1 million winning tickets, the information was transcribed incorrectly,” Michael Sweeney, executive director of the Massachusetts State Lottery, said in a statement. “We apologize for the confusion this created and remain thrilled that a jackpot winning ticket and two $1 million winning tickets were sold here in Massachusetts.”

Reportedly, 34 people won a million each in the Wednesday drawings. The last person to win an actual Powerball jackpot in Massachusetts was in 2013.

The 53-year-old Wanczyk revealed during the press conference that she has two adult children. Asked whether she had been well off financially, Wanczyk said she could not say she was the richest or poorest person she knew, but rather that she was middle class. She revealed she was just finishing up payments on a car she bought in September of last year — a loan payment she’ll, no doubt, no longer need to worry about anymore, ever.

Either wrapped up in nerves or shock or perhaps even getting used to the relaxed lifestyle of someone worth hundreds of millions, Wanczyk awkwardly chewed gum throughout her press conference. It must have raised some eyebrows with the press and viewers — but when you’ve just won over $750 million (before Uncle Sam takes his hefty cut), who cares what anybody thinks?

Chew away!
