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)

The equation that represents the number of residents surveyed is 2/5r = 80. According to this equation, 80 residents represent two-fifths of the total number of residents surveyed. To find the total number of residents surveyed, we can isolate r by multiplying both sides of the equation by 5/2: r = 80 * (5/2) = 200. Therefore, 200 residents were surveyed.
