(CNN) Former food company executive Michelle Janavs was sentenced Tuesday to five months in prison for paying bribes in the college admissions scam, the US Attorney's Office in Massachusetts said.

Janavs, whose family invented Hot Pockets, paid the scheme's mastermind, Rick Singer, $100,000 to cheat on two of her daughters' ACTs, and agreed to pay $200,000 to have one of the daughters admitted to University of Southern California as a "fake beach volleyball recruit," according to a sentencing memorandum.

Janavs, 49, was one of four defendants who are "far and away the most culpable parents" in the admissions scandal, the memorandum states. Janavs and the three others are "repeat players, who engaged in the conspiracy again and again, over years."

Janavs in October pleaded guilty to conspiracy to commit mail and wire fraud and conspiracy to commit money laundering.

She also was ordered to pay a $250,000 fine and to serve two years of supervised release after prison, said Liz McCarthy, spokesperson for the US Attorney's Office.
