Professor Harrington took a sample of metal and measured how many kilograms of each metal were present. The professor found 14.52 kilograms of aluminum, 9.9 kilograms of lead, and 1.137 kilograms of silver. How many kilograms was Professor Harrington's sample?

Answer 1

The total weight of the sample is the sum of the weights of the individual metals.

Total weight = 14.52 kg + 9.9 kg + 1.137 kg

Total weight = 25.557 kg

Professor Harrington's sample weighed 25.557 kilograms.
