A certain industrial machine requires 20 quarts (640 ounces) of oil every day, and it is given a mixture of oil A and oil B. Oil A consists of 5% special additives while oil B consists of 9% special additives. If the machine needs exactly 50 ounces of the special additives to ensure smooth operation, then how much of oil A, in ounces, should be in the mixture?
