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)
5/2 * r = 80; 200 residents were surveyed.
2/5 * r = 80; 32 residents were surveyed,
80r = 2/5 200 residents were surveyed.
о 2/5 * r = 80 200 residents were surveyed.
The equation that represents the number of residents surveyed is: 2/5 * r = 80. From this equation, we can solve for r by multiplying both sides by 5/2:
r = (80 * 5/2) = 200.
Therefore, 200 residents were surveyed.
