Callaway Golf is trying to determine how the price of a set of clubs affects the demand for clubs. The attachedimagecontains the price of a set of clubs (in dollars) and the monthly sales (number of sets sold).

1. Assume the only factor influencing monthly sales is price. Fit the following two curves to these data: linearand exponential. Which equation best fits the data?

2. Interpret your best-fitting equation.

3. Using the best-fitting equation, predict sales during a month in which the price is $470.

Price Demand $400 20.000 $420 19.000 $440 17.000 $460 16.000 $500 14.000 $380 22.000 $290 31.000 $340 26.000 $220 41.000 $700 6.000
