Answer:
The percent of decrease is [tex]30\%[/tex]
Step-by-step explanation:
Assuming the number of students enrolled in the photography club decrease from 50 to 35.
Then the change in student enrollment is 35-50=-15.
The percent of change is given by:
[tex]\frac{Change\:in\:enrollment}{Original\:number}\times 100\%[/tex]
[tex]\frac{-15}{50}\times 100\%[/tex]
[tex]-15*2\%=-30\%[/tex]
