This question has the same context as the last two questions, but a different set of data was used to fit the following curvilinear models. Remember that y represents coffee sales (in 100s of gallons) and x represents the number of dispensers. Exponential: y = 611.86e^(0.055x) Logarithmic: y = 132.42ln(x) + 605.27 Power: y = 610.697x^(0.181) Polynomial: y = -5.93x^2 + 88.01x - 533.13 Use a power model to predict sales when 6 dispensers are used.
