Answer:
91.96%.
Explanation:
We have been given that during the World Series the host city wide hotel occupancy rose 21% over the prior busiest night. The busiest night had been 76% occupancy.

To find the new record of occupancy, we will find 21% of 76% and add it to 76%.





Now let us convert our answer in percentage by multiplying our answer by 100.

Therefore, the new record of occupancy was 91.96%.
