Dual federalism is also referred to as 'layer cake' federalism due to the clear presence of layer in the cake. In the cooperative federalism, the line of distinction between the powers and responsibilities of the national government and the state governments is blurred.
The problem starts already earlier:wildlife experts can only estimate the number of species in the world generally!
This is the case because there are simply too many species, and it takes time to documents them; because some areas (ocean bottom for example) are very hard to access and because sometimes it's hard to know whether we're talking about a new species or a variation within the same species.
so if we even don't know how many species there are, it's even harder to know how many are endangered.
Answer:
2/6 = 2 shillings sixpence or about 68 US cents, equivalent to $15.96 today. 5/- = 5 shillings (no pence) or about $1.35 in the US in 1900, which would be equivalent to $32.40 today. So, back then Bob would be able to buy anything that would be worth $225 in the U.S.
