Suppose a firm faces the following demand curve: q(p) = 10000 - 800p Also the varaible cost per unit is $5 and the fixed cost is $10000. The firm will charge a price of $8.75

1. What will the profit be at a price of $8.75

2. What is the price elasticity of demand?

3. At what price will an increase in price lead to revenue falling instead of rising.

Homework Answers

Answer #1
1 q(p)=10000-800p
q(p)=10000-800*8.75= 3000
Revenue 26250 =3000*8.75
Less: Variable cost 15000 =3000*5
Contribution Margin 11250
Less: Fixed Cost 10000
Net Income 1250
2 Price Elasticity=percentage change in demand/percentage change in price -2.33 =(20/-8.57)
P 8.75
Q 3000
Assume p1 8
Q1 3600 =10000-800*8
Percentage change in demand=(Q1-Q)/Q 20.00% =(3600-3000)/3000*100
Percentage change in price=(P1-P)/P -8.57% =(8-8.75)/8.75*100
3 At 8.75 increase in price will lead to decrease in revenue since PED is elastic. When Price elasticity is elastic then increase in price result in decraese in revenue.

1Suppose the firm is a monopolist. It faces a downward-sloping demand curve, P(Q). If it also has non-negative marginal cost, will it choose a quantity on the demand curve where the price elasticity of demand is less than, greater than, or equal to -1? Explain. 2. Now, consider what will happen if a firm has exactly one competitor in the market. Both firms have identical technologies and cost structures (assuming a constant marginal cost may be helpful), and each chooses...
