Answer:
15% decrease in annual number of performances
Step-by-step explanation:
first, we can label 340 as 100%, and determine what percentage 289 is if 340 is 100%. To do this, we can divide 289 by 340
[tex]\frac{289}{340} = 0.85[/tex]
To convert a decimal into percentage, we multiply by 100
[tex]0.85*100 = 85%[/tex]
as 289 performances is 85% of 340, we can see the percentage of decrease is 100% - 85% = 15%
Therefore, the percent of decrease in the annual number of performances is 15%
