Data Analysis - Elementary School Math

A shirt manufacturing company manufactures three colored shirts. The circle graph below shows the percentages of each color that is produced. Based on the graph, what percent of blue shirts are produced?


Answer:

30% Blue Shirts

In order to solve this problem, the student must add the total percent of red shirts and white shirts produced and subtract that from 100%. The answer will give the total percent of blue shirts produced. The steps are as follows:


60 % white shirts + 10% red shirts = 70 % shirts out of the total

100 % total shirts – 70 % shirts produced = 30 % blue shirts that are produced.
