Question #54449

1.There is a fruit seller who has 30 Kgs of apples to be sold and he wants to fix a price so that all the apples are sold. There are three customers in the market and their individual demand functions are given below:

D1=25-.05P

D2=20-.025P

D3=15-.075P

Where D is the demand and P is the price

Determine

Market demand equation for the fruit seller

Price at which he can sell all the apples

Individual demands of each of the three customers

2. A) Determine the market equilibrium price if the demand and supply function is given as:

D = 12p + 8

S = 14p – 4

Where D= demand

S=supply

p= price

B) Determine the equilibrium quantity if price is the same as above

D = 4p – 4q

S = 8q – 4p

Where D= demand S=supply p=price q=quantity

D1=25-.05P

D2=20-.025P

D3=15-.075P

Where D is the demand and P is the price

Determine

Market demand equation for the fruit seller

Price at which he can sell all the apples

Individual demands of each of the three customers

2. A) Determine the market equilibrium price if the demand and supply function is given as:

Expert's answer

1) If Qs = 30 Kgs of apples to be sold and

there are three customers in the market and their individual demand functions are given below:

D1=25-.05P

D2=20-.025P

D3=15-.075P

Then the market demand equation for the fruit seller is: D = D1 + D2 + D3 = 60 ¬ 0.15P

D = S, so:

60 - 0.15P = 30,

0.15P = 30,

P = $200 is the price at which he can sell all the apples.

The individual demands will be:

D1 = 25 - .05*200 = 15 units

D2 = 20 - .025*200 = 15 units

D3 = 15 - .075*200 = 0 units

2) a) D = 12p + 8

S = 14p – 4

Equilibrium price is in the point, where Qd = Qs, so:

12p + 8 = 14p - 4

p = $6

b) The equilibrium quantity is in the point, where Qd = Qs, so if p = 6, then:

D = 4p – 4q

S = 8q – 4p

24 - 4q = 8q - 24

q = 4 units.

there are three customers in the market and their individual demand functions are given below:

D1=25-.05P

D2=20-.025P

D3=15-.075P

Then the market demand equation for the fruit seller is: D = D1 + D2 + D3 = 60 ¬ 0.15P

D = S, so:

60 - 0.15P = 30,

0.15P = 30,

P = $200 is the price at which he can sell all the apples.

The individual demands will be:

D1 = 25 - .05*200 = 15 units

D2 = 20 - .025*200 = 15 units

D3 = 15 - .075*200 = 0 units

2) a) D = 12p + 8

S = 14p – 4

Equilibrium price is in the point, where Qd = Qs, so:

12p + 8 = 14p - 4

p = $6

b) The equilibrium quantity is in the point, where Qd = Qs, so if p = 6, then:

D = 4p – 4q

S = 8q – 4p

24 - 4q = 8q - 24

q = 4 units.
