Question # 2: Dentists use various amalgams for silver fillings. The matrix shows the percentages expressed as decimals) of powdered alloys used in preparing three different amalgams. Suppose a dentist has 5483 grams of silver, 2009 grams of tin, and 129 grams of copper. How much of each amalgam can be made? Convert it into a system of linear equations and solve using Cramer's rule. PERCENT ALLOY BY WEIGHT Amalgam B A C Silver [0.70 0.72 0.73] Tin |0.26 0.25 0.27 Copper 0.04 0.03 0.00
