A.) How many students participated in dance?
Based on the chart, 25% of the students participated in the dance. Let's determine the actual number out of 200 students:
![\text{ 25\% of 200 = 200 x }(25)/(100)\text{ = 200 x 0.25 = 50 Students}](https://img.qammunity.org/2023/formulas/mathematics/high-school/fl5hqvkc1kmxmvwte22wmo87i3h41seuu5.png)
Therefore, there are 50 Students that participated in the dance.
B.) How many more students participated in Dodgeball than in Basketball?
![\text{ (200)(}(40)/(100))\text{ - (200)(}(25)/(100))\text{ = (200)(0.40) - (200)(0.25)}](https://img.qammunity.org/2023/formulas/mathematics/high-school/lvcvbaj0fhi9p93r55wxxzav3snu50ixmv.png)
![\text{ = 80 - 50}](https://img.qammunity.org/2023/formulas/mathematics/high-school/zay8kwgsn12xu5a565pxqdiqgridq0wrhv.png)
![\text{ = 30 Students}](https://img.qammunity.org/2023/formulas/mathematics/high-school/b6syfao0ott78vs4783m8whk1yqhhrb3dw.png)
Therefore, there are 30 more students that participated in Dodgeball than in Basketball.
