The correct equation is "25r = 80". This equation represents the number of residents surveyed. To find out how many residents were surveyed, we can solve this equation for r:
25r = 80
Dividing both sides by 25:
r = 80/25
Simplifying the fraction:
r = 16/5 = 3.2
Therefore, 3.2 represents the number of residents surveyed. However, since it doesn't make sense to have a fraction of a resident, we round up to the nearest whole number. So, 4 residents were surveyed.
None of the given options accurately represent the equation or the number of residents surveyed.
