A car company performed an experiment to accurately describe their new vehicle's gas mileage. The table below shows the car's speed in miles per hour and the mileage of the vehicle. Use a graphing calculator (or Microsoft Excel) to find a model that best fits the data. Then, use the model to find the mileage of the car traveling 85 miles per hour. Be sure to use the equation editor to type your answer. Round all values to the nearest thousandth. Speed, x Mileage, y 15 22.3 20 25.5 25 27.5 30 29.0 35 28.8 40 30.0 45 29.9 50 30.2 55 30.4 60 28.8 65 27.4 70 25.3 75 23.3
