Andy is a $$rm believer in waking up early each morning to start his day. His passion for waking up early drove him to start his own business of making alarm clocks for deep sleepers. He knows that total monthly demand next month exceeds his capacity available for production. He produces $3$ types of alarm clocks: vibrating, sunrise and foghorn. Each of these $3$ alarm clock models pass through $3$ stations in the assembly process. Andy estimates demand for next month to be $140$ units of Vibrating clocks, $170$ units of Sunrise clocks, and $195$ units of Foghorn clocks. Andy's Alarms operates two $4-$hour shifts per day and are scheduled to work $20$ days next month. Additionally, each station requires a $10\%$ capacity cushion. What is the total number of units of Foghorn alarms produced?
