A store sells both cold and hot beverages. Cold beverages, c, cost $1.50, while hot beverages, h, cost $2.00. On Saturday, drink receipts totaled $360, and 4 times as many cold beverages were sold as hot beverages.
 Which system of linear equations represents the beverage sales on Saturday?
 4c = h
 1.5c + 2h = 360
 c = 4h
 1.5c + 2h = 360
 c + h = 360
 1.5c = 4(2h)
 c + h = 360
 4(1.5c) = 2h
