To find the percentage of the Jefferson nickel that is made up of silver, you can subtract the percentages of copper and manganese from 100%.

You have:

  • Copper = 56%
  • Manganese = 9%

First, add the percentages of copper and manganese: 56% + 9% = 65%

Next, subtract this sum from 100% to find the percentage of silver: 100% - 65% = 35%

Therefore, the percentage of the Jefferson nickel that is made up of silver is 35%.
