A survey is conducted in a certain neighborhood to find out residents’ favorite vacation spot. Two-fifths of the respondents, or 80 residents, said they like spending their vacation at the beach. Which equation represents the number of residents, r , surveyed? How many residents were surveyed?(1 point)
5/2r=80; 200 residents were surveyed.
80r=2/5; 200 residents were surveyed.
2/5r=80; 200 residents were surveyed.
2/5r=80; 32 residents were surveyed.
The correct equation is 2/5r = 80.
To find the number of residents surveyed, we can solve this equation for r.
Multiplying both sides of the equation by 5/2 gives us r = 200.
Therefore, 200 residents were surveyed.
So, the correct answer is:
2/5r=80; 200 residents were surveyed.
