Question

Professor Morton took a sample of metal and measured how many kilograms of each metal were present. The professor found 84.2 kilograms of aluminum, 27.1 kilograms of lead, 47.007 kilograms of silver, and 0.81 kilograms of palladium. How many kilograms was Professor Morton's sample?

Answer 1

To find the total kilograms of the sample, we add up the kilograms of aluminum, lead, silver, and palladium: 84.2 + 27.1 + 47.007 + 0.81 = <<84.2+27.1+47.007+0.81=159.117>>159.117 kilograms. Answer: \boxed{159.117}.
