Question

 This​ week, 977 people went to the beach. Last​ week, 1 comma 231 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 from last week to this week, you can use the following formula:

\[
\text{Percentage Decrease} = \left( \frac{\text{Last Week's Attendance} - \text{This Week's Attendance}}{\text{Last Week's Attendance}} \right) \times 100
\]

1. Last week's attendance: 1,231
2. This week's attendance: 977

Now, plug in the values:

\[
\text{Percentage Decrease} = \left( \frac{1231 - 977}{1231} \right) \times 100
\]

Calculate the difference:

\[
1231 - 977 = 254
\]

Now, substitute this back into the formula:

\[
\text{Percentage Decrease} = \left( \frac{254}{1231} \right) \times 100
\]

Calculate the fraction:

\[
\frac{254}{1231} \approx 0.206
\]

Now, multiply by 100 to convert to a percentage:

\[
0.206 \times 100 \approx 20.6
\]

Therefore, the number of people who went to the beach fell by approximately **20.6%**.
