The answer is "<span>Franz Gall."
</span>Gall is famously known as the most understood researchers of the eighteenth century, Franz Josef Gal was a famous anatomist, and physiologist. He was most broadly known for his ideas of localised capacities in the brain, and cranioscopy (later alluded to as phrenology).
The marginal cost is how much it costs to produce one item more. It cost 0$ to produce 0 bikes but if you make one, then it costs 80$. Hence the marginal cost for the first bike is 80$. For the fourth bike, we have that the 3 bikes cost 110$ and the 4 bikes cost 130$. Hence it costs 20$ dollars to produce one more bike (from 3rd to 4th) and hence the marginal cost is 20$. Similarly for the 6th bike, we compare the cost of producing 5 bikes to the cost of producing 6 bikes and we get that the marginal cost is 50$. Applying the same methodology, the marginal cost for the 7th bike is 60$.
In completion of your question:
Calculate how many fish they can catch and how many huts they can build on their own in one year
Answer:
Bagley can catch 180 fish and build 90 huts.
Spano can catch 120 fish and build 40 huts
Explanation:
If Bagley spends all her time just catching fish in one year she can catch 180 fish (1800 hrs/10 hrs per fish), on the other hand if she spends all her time making huts she can make 90 huts (1800hrs/ 20 hrs per hut) in one year. If Spano spends all his time just catching fish in one year he can catch 120 fish. On the other hand, if he spends all his time making huts in one year he can make 40 huts.
The answers were each gotten by dividing the total number of hrs worked(1800) by each person's rate(such as bagley's 10hr/fish).
