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%.
