A cafe recorded the number of iced drinks it sold, \(y\), on several days, along with that day's high temperature, \(x\), in degrees Fahrenheit. The table shows the data for four of those days.

High temperature (\(^{\circ}\)F), \(x\)Iced drinks sold, \(y\)
\(78\)\(128\)
\(85\)\(165\)
\(90\)\(175\)
\(98\)\(205\)

Using all of the data, a line of best fit is given by \(y = 4x - 180\). Based on this model, how many iced drinks should the cafe expect to sell on a day when the high temperature is \(95\,^{\circ}\)F?
