Elizabeth, a jeweler, makes two types of rings. One type of ring, the Goldenrod, is made from 2 grams of platinum and 6 grams of gold. Another ring, the Oracle, is made from 8 grams of platinum and 1 gram of gold. Her supply shipment for the next week has 80 grams of platinum and 79 grams of gold. If she uses all of her supplies to make a total of 19 rings, how many of those rings would be Oracles?
