I have been able to get A and B answered correctly, however C is something I just cannot figure out and my instructor has not responded since Wednesday.

The table below compares the price of an ipod Touch with how many units are sold per week. Price p ($) Weekly Sales S 150 206700 170 198900 190 194040 210 190820 A. Use linear regression on your calculator to find the linear model that best fits this data. Use p (lowercase) as your variable, not x, and round to 2 decimal places. S = Preview B. According to your model, predict the weekly sales volume S if the price of an ipod Touch is p = $7 ? Round to the nearest 100. S = C. According to the model, what price p would create a weekly sales volume of S = 199, 978? Round to the nearest $1 p = $
