Lacks fenestrae makes a triceratops unique when comparing it to other Ceratopsidae.
Triceratops is characterized via a quick frill with a flat squamosal, an upturned caudal margin of the frill, the absence of fenestrae, and a midline epiparietal. Torosaurus is characterized by using an elongate frill with a straighter facet, a concave squamosal, and a shortage of upturning of the frill.
A year-long study by Yale university paleontologists concludes that two associated horned dinosaurs are different animals and not adult and juvenile versions of the same.
Now Scannella and Horner say that triceratops is simply the juvenile form of torosaurus. As the animal elderly, its horns changed shape and orientation and its frill became longer, thinner and less jagged. Eventually, it became fenestrated, producing the traditional torosaurus form.

Answer:
(a):Annual demand = 10 packages per day*260 days per year = 2600 packages per year.
H = $1 and S = $10.
Thus Order quantity = (2*2600*10/1)^0.5 = 228 packages
(b): Total annual inventory control cost = Q/2*H + D/Q*S
= 228/2*1 + 2600/228*10
= 114 + 114.03
= 228.03
(c): Yes both annual ordering costs and holding costs are equal at $114.
(d): In case of order quantity of 100 packages the cost will be = 100/2*1 + 2600/100*10
= 50 + 260
= 310.
Thus the cost figure of $310 in case of 100 packages is more than the cost of $228.03 when 228 packages are ordered. Hence I will recommend that the office manager use the optimal order quantity instead of 100 packages.
Solution :
Given the wage = $ 10.25 that is to be imposed to the market.
Given equation :
= 500 – 45W and 
= -200 + 25W
If the wage of $10.25 is to be imposed to the market, the value of the labor supply can be found by putting the value of the wage in the labor supply equation.
At W = 10.25
Putting this value in the above equation, the labor supply would be
= -200 + 25W
= -200 + 25(10.25)
= 56.25
When W = 10.25, the value for the labor demand can be found by :
= 500 – 45W
= 500 – 45(10.25)
= 500 – 461.25
= 38.75
Therefore, the labor demand and the labor supply model is
= 400 - 45 x 10.25
= -200 + 25 x 10.25
