1. The problem states that the line of best fit for attendance based on high temperature is given by the equation $$y = 2.5x - 50$$ where $x$ is the high temperature in °F and $y$ is the attendance. 2. We want to find the attendance for a day with a high temperature of 80°F using the equation. 3. Substitute $x = 80$ into the equation: $$y = 2.5(80) - 50$$ 4. Calculate the multiplication: $$y = 200 - 50$$ 5. Simplify the subtraction: $$y = 150$$ 6. This means on a day with a high temperature of 80°F, the attendance would likely be about 150 people. 7. Therefore, the statement "On a day with a high temperature of 80°F, the attendance would likely be about 150 people" is true. 8. For reference, the attendance at 60°F can be calculated similarly: $$y = 2.5(60) - 50 = 150 - 50 = 100$$ So the attendance at 60°F would be about 100 people, not 150. Hence, the correct statement is about the attendance at 80°F being about 150 people.
