Flannery is a wizard brewing a batch of potions. She wants to brew some luck potions and some flight potions. Each contains the same rare specialized ingredients, dove feather dust and purple snake scales. A luck potion uses 3 pinches of dove feather dust and 2 purple snake scales. A flight potion uses 2 pinches of dove feather dust and 5 purple snake scales.
Flannery has 24 pinches of dove feather dust and 38 purple snake scales available. She wants to use all of the ingredients without leftovers.
Find the amount of each potion Flannery should make to use all of her supplies,
After Flannery gets her ingredients out of the cellar, her familiar, orange cat named Ferguson, knocks over the jar of dove feather dust, spilling 4 pinches onto the floor and rendering them unusable. Flannery decides to brew fewer potions, but keep the same ratio of luck to flight potions. She cannot partially brew a potion.
