(Expоnentiаl Mоdels MC)Dаtа were cоllected in the summer from a group of park rangers about the temperature outside, ranging from 65 to 100 degrees Fahrenheit, and attendance at the park. The results were used to calculate the model ŷ = 23(1.047)x, where x represents the temperature in degrees Fahrenheit and ŷ represents the predicted number of visitors. Using the model, how many visitors would a 65-degree day be predicted to bring?
