(Linear Models MC)Data were collected from several hospitals about the charge for medical procedures and the popularity of the procedures. The results were used to calculate the model ŷ = –58.25x + 927, where x represents the cost of the procedure in thousands of dollars and ŷ represents the predicted number of procedures performed. Using the model, how much would a procedure cost that is predicted to be performed 400 times?

(Exponential Models MC)Data were collected 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 = 19(1.051)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 75-degree day be predicted to bring?
