A Waterloo woman said a $100,000 Powerball prize will help her reach her goal of paying off her home mortgage.

“It shaved 20 years off of my mortgage, so it’ll get paid off in seven years instead of almost 30,” Sarah Baxter told officials on Tuesday as she claimed her prize at lottery headquarters in Clive. Baxter, 37, matched four of five white balls and the Powerball in last Saturday’s drawing. That mean a $50,000 prize, was doubled because she opted for the $1 Power Play add-on, which multiples non-jackpot prize amounts by up to 10 times.

She purchased her winning ticket at Road Ranger, 100 Plaza Drive in Elk Run Heights. Baxter said she checked her numbers online after the drawing and almost fainted. “It just doesn’t feel real,” she said. “It’s a huge weight off my shoulders.”

The winning numbers in Saturday’s drawing were 3-21-23-31-59 and Powerball 3. The Power Play was 2. No one won the jackpot, so this Saturday's jackpot stands at an estimated $321 million.
