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?

Answer 1

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%.
