## Basic College Mathematics (10th Edition)

(a) The number of degrees in a circle for each item can be found multiplying the percent of each category to 360 degrees: Travel: $=50\% \cdot 360 = 0.50 \cdot 360 = 180$ degrees Apparel, accessories, and footwear: $=20\% \cdot 360 = 0.20 \cdot 360 = 72$ degrees Computer hardware and software: $=15\% \cdot 360 = 0.15 \cdot 360 = 54$ degrees Autos and auto parts: $=10\% \cdot 360 = 0.10 \cdot 360 = 36$ degrees Home furnishings: $=5\% \cdot 360 = 0.05 \cdot 360 = 18$ degrees (b) Make a circle graph by using the degree measure of each category. Use a protractor for accurate circle graph and label the parts. (Refer to the circle graph in the answer part above.)
