Tataru has decided the best place to source her materials, so she gets to work making rings. She buys crystals, silver bars and gold bars. If she wishes to use all of her resources efficiently, how many rings of each type can she make? Remember: Crystal rings use two crystals and two silver bars. Gold rings use three crystals and one gold bar. Silver rings use three silver bars and one gold bar. Let X: Crystal Rings, Y: Gold Rings, Z: Silver Rings. b One week later, Tataru has crystals, silver bars and gold bars. If she wishes to use all of her resources efficiently, how many rings of each type can she make? c Feeling like it's inefficient to work out the calculations every week, Tataru asks you to create a matrix that represents the materials needed to make each ring, and then find the inverse of that matrix. d If Tataru has C crystals, S silver bars and G gold bars, create a formula for her to determine how many rings of each type she can make
