Need help to complete the table to determine total demand per station. which station is the bottle neck? how do I calculate utilization rate? how many more powersmart can I produce?

A lawn mower factory manufacture five top-selling models named Greenworks, Toro Recycler, Eco Walker,

Powersmart and Craftsman. The following table shows how long it takes to process each lawn mower through

each required station (in minutes). The factory open 18 hours a day, 6 days a week and 9 hours on Sunday.

		Greenworks	Toro Recycler	Eco Walker	Powersmart	Craftsman	Total load (min)
Weekly demand		400	100	200	300	300
Process time station 1		6	5	0	8	3
Process time station 2		4	4	5	2	3
Process time station 3		5	7	4	2	2
Process time station 4		4	3	9	1	6
3. If weekly demand for the five products are now: 400, 100, 200, 300 and 300 respectively, which station is the bottleneck,
and is it capable of producing all the law mower demanded (if so what is the utilization rate)?
How many additional Powersmart could be produced?
