On its first day of business, the Icey’s Ice-Cream Store sold two sizes of ice-cream cones, one scoop for $0.80 and two scoops for $1.25. They sold 400 scoops of ice cream in cones for a total revenue of $250.00. At the end of the day, the manager wondered how many one-scoop and how many two-scoop cones they had sold, but no one had kept track. Help the manager out! Determine how many one-scoop and how many two-scoop cones were sold. (Hint: Asking for SCOOPS not cones!)
