Wham-o makes 3 plastic toys; hula-hoops (product h), strawshooters (product s), and wingdingers (product w). wham-o has 4 resource types that are used in production - the process times required to make each toy at each resource type (and the number of processors of each type) are shown in the table below. for example, hula-hoops must go through extrusion, forming and packaging (but hula-hoops do not require any process time at the "finishing" step). each resource is operated 10 hours each day.
for example, in one hour, extrusion can process 40 hula-hoops if it only works on hula-hoops (i. e., one every 3 minutes, so 20 per hour, for each of the two processors), or it can process 30 straw-shooters if it only works on straw-shooters, or it can process 60 wing-dingers if it only works on wing-dingers (alternately, it can process some combination of h, s, and w). if demand for hula-hoops and strawshooters is 0 units per day; and for wing-dingers is 400 units per day, then which resource is the bottle-neck?
a) extrusion, forming, and packaging have the same output per hour, so they are all bottle-necks
b) extrusion
c) forming
d) packaging
