Question

 This​ week, 963 people went to the beach. Last​ week, 1 comma 169 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, we can use the following formula:

\[
\text{Percentage Decrease} = \frac{\text{Old Number} - \text{New Number}}{\text{Old Number}} \times 100
\]

In this case:
- The old number (last week) is 1,169.
- The new number (this week) is 963.

Now, plug the values into the formula:

\[
\text{Percentage Decrease} = \frac{1169 - 963}{1169} \times 100
\]

First, calculate the difference:

\[
1169 - 963 = 206
\]

Next, divide by the old number:

\[
\frac{206}{1169} \approx 0.1762
\]

Now, multiply by 100 to convert it to a percentage:

\[
0.1762 \times 100 \approx 17.62
\]

Thus, the number of people who went to the beach fell by approximately **17.62%**.
