(a)

Answer to Problem 34PPS
Here, 12.5% of the students surveyed said their favorite act was playing instruments.
Explanation of Solution
Given:
Act | Number of Student |
Stand-up comedy | 198 |
singing | 150 |
dancing | 212 |
Playing instruments | 80 |
Calculation:
Act | Number of Student | Percent |
Stand-up comedy | 198 | |
singing | 150 | |
dancing | 212 | |
Playing instruments | 80 |
12.5% of the students surveyed said their favorite act was playing instruments.
Conclusion:
Hence, 12.5% of the students surveyed said their favorite act was playing instruments.
(b)
To find: whether the percent is greater than, less than, or equal to the current percent.
(b)

Answer to Problem 34PPS
New percent will be greater than to the current percent.
Explanation of Solution
Given:
10 more students vote up for stand-up comedy.
Calculation:
If 10 more students vote for stand-up comedy.
Conclusion:
Therefore, new percent will be greater than to the current percent.
