  • Last week's attendance = 1,211
  • This week's attendance = 971

Now, calculate the decrease in attendance:

Decrease=1,211971=240

Now plug this value into the percentage decrease formula:

Percentage decrease=(2401,211)×100

Calculating:

Percentage decrease0.1976×10019.76

Therefore, the number of people who went to the beach fell by approximately 19.76%.
