Explanation:

Part A. What percent preferred a color other than blue, white, red, black, or silver?

Percent = 100 - 32 - 24 - 20 - 18 - 4

Percent = 100 - 98

Percent = 2%

2% preferred a color other than blue, white, red, black, or silver

Part B. How many more people said their favorite color is white compared to those who said black?

Percent = 24 - 18

Percent = 6%

6% more people said their favorite color is white compared to those who said black

Part C. Draw and label a circle graph showing the responses to the survey. Be sure to include a section for “Other”. Be sure your circle graph is labeled, and the percentages are in proportion to the whole.
