Suppose Jim has a demand curve​ of:

QJd=8 − p​,

and Sam has a demand curve​ of:

QSd=6 − 0.5p.

How much is the total demand at a price of $8.50​?   unit(s) ​(round your answer to two decimal​ places).

How much is total demand at a price of​$7.00​?   unit(s)​(round your answer to two decimal​ places).

Solutions

Expert Solution

The market demand function defines total demand in the market, and it is derived by adding up individual demand in the market.

Here, Demand function of Jim is QJd=8 − p​,

Demand function of Sam is QSd=6 − 0.5p.

Therefore, the market demand function would be:

1) At price $8.50, total demand would be:

2) At price $7.00, total demand would be:

Suppose that one individual’s demand curve is D1(p) = 20−p and another individual’s is D2(p) = 10−2p. What is the market demand function? We have to be a little careful here about what we mean by “linear” demand functions. Since a negative amount of a good usually has no meaning, we really mean that the individual demand functions have the form D1(p) = max{20 − p, 0} D2(p) = max{10 − 2p, 0}. What economists call “linear” demand curves actually...
