A population researcher has found that the population P (in thousands) of a city in a particular year is a function of the number N (in thousands) of the jobs available in that year which is, in turn, a function of the economy E (in billions of dollars) of the state in which that city is located. The researcher has determined that for a particular year, E=204, dP/dN=8, and dN/dE=0.4.

Find dP/dE.

At E=204, the population increases by thousand people for each billion dollar increase in the state's economy.

At E=204, the population increases by 3.2 thousand people for each billion dollar increase in the state's economy.

Step-by-step explanation:

Given : A population researcher has found that the population P (in thousands) of a city in a particular year is a function of the number N (in thousands) of the jobs available in that year which is, in turn, a function of the economy E (in billions of dollars) of the state in which that city is located.

To find : The value of ?

Solution :

The researcher has determined that for a particular year,

E=204, , and .

Using chain rule,

At E=204, the population increases by 3.2 thousand people for each billion dollar increase in the state's economy.

the answer is 0.3175 hope that you ^w^
