Answer 1

To solve the problem, we start with the information given: two-fifths of the respondents, or 80 residents, like spending their vacation at the beach.

This can be expressed mathematically. If \( r \) represents the total number of residents surveyed, then two-fifths of \( r \) can be written as:

\[ \frac{2}{5}r = 80 \]

To find \( r \), we can multiply both sides of the equation by \( \frac{5}{2} \):

\[ r = 80 \times \frac{5}{2} = 80 \times 2.5 = 200 \]

So, the total number of residents surveyed is 200.

Now, looking at the provided options, the correct equation that represents the relationship is:

\[ \frac{2}{5}r = 80; \text{ 200 residents were surveyed.} \]

Thus, the correct choice is:

Start Fraction 2 over 5 End Fraction r = 80 ; 200 residents were surveyed.
