We can calculate the percent change dividing the change by the original amount of people attending the exhibit.
The increase is 298-152 = 146.
Then, we can calculate the percent change as:
![(298-152)/(152)=(146)/(152)=0.9605=96\%](https://img.qammunity.org/2023/formulas/mathematics/college/7ofxn4jblv9aief65883gzt210hynykmsp.png)
There was a 96% increase in the number of people attending the exhibit.
