Final answer:
The percent change is 25%. The scenario represents a percent increase.
Step-by-step explanation:
The percent change can be calculated using the formula:
Percent Change = ((New Value - Old Value) / Old Value) * 100%
In this scenario, the old value is $30 and the new value is $37.50. Therefore, the percent change is ((37.50 - 30) / 30) * 100% = 25%.
Since the value of the coin increased from $30 to $37.50, the scenario represents a percent increase.
Hence, the true statements are:
- The percent change is 25%.
- The scenario represents a percent increase.
