Marty's grandmother cans spaghetti sauce. Last year she canned some specifically for Marty. She ended up with 25 quarts full. Marty noticed, however, that a quart of sauce is too much for her meals (she only cooks for herself). If she wants her grandmother to can the sauce in pints this year, how many pint jars should she buy to put it in?
