Use the image to answer the question.
A circle graph is divided into 3 sections. The value for copper is 56 percent. The value for manganese is 9 percent. The section labeled silver is not assigned a percentage value.
The circle graph represents the breakdown of metals in a Jefferson nickel. Each category is represented as a percentage of the total volume of the coin. What percentage of the Jefferson nickel is made up of silver?
To find the percentage of the Jefferson nickel that is made up of silver, we need to first calculate the total percentage of the other two metals (copper and manganese) combined.
Copper = 56%
Manganese = 9%
Total percentage of copper and manganese = 56% + 9% = 65%
Since the circle graph represents the breakdown of metals in the Jefferson nickel and the total volume should be 100%, we can subtract the total percentage of copper and manganese from 100% to find the percentage of silver.
100% - 65% = 35%
Therefore, 35% of the Jefferson nickel is made up of silver.
