Reasoning  This​ week, 971 people went to the beach. Last​ week, 1 comma 211 people went to the beach. The number of people who went to the beach fell by what​ percent?

1 answer

To find the percentage decrease in the number of people who went to the beach, you can use the following formula:

\[ \text{Percentage decrease} = \left( \frac{\text{Last week's attendance} - \text{This week's attendance}}{\text{Last week's attendance}} \right) \times 100 \]

Plugging in the numbers from your question:

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

Now, calculate the decrease in attendance:

\[ \text{Decrease} = 1,211 - 971 = 240 \]

Now plug this value into the percentage decrease formula:

\[ \text{Percentage decrease} = \left( \frac{240}{1,211} \right) \times 100 \]

Calculating:

\[ \text{Percentage decrease} \approx 0.1976 \times 100 \approx 19.76 \]

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