Build the whole regression line from summaries, then predict

A study relates weekly advertising spend ($x$) to units sold ($y$). You never see the raw data, only these five summaries:

$\bar{x} = 50, \quad \bar{y} = 140, \quad s_x = 10, \quad s_y = 30, \quad r = 0.8.$

Using only these, predict the units sold when spend is $x = 60$.
