Suppose QX d = 10,000 – 2 PX + 3 PY – 4.5M , where PX = $100, PY = $50, and M = $2,000. How much of good X is consumed?
  • 950 units

Suppose QX d = 10,000 – 2 PX + 3 PY – 4.5M , where PX = $100, PY = $50, and M = $2,000. Then good X has a demand which is:

  • Inelastic
Suppose QX d = 10,000 – 2 PX + 3 PY – 4.5M , where PX = $100, PY = $50, and M = $2,000. What is the own-price elasticity of demand?
  • -0.21

If a price increase from $5 to $7 causes quantity demanded to fall from 150 to 100, what is the absolute value of the own-price elasticity at a price of $7?

  • 1.75
If the absolute value of the own-price elasticity of steak is 0.4, a decrease in price will lead to:
  • A reduction in total revenue

If quantity demanded sneakers falls by 10% when price increases 25% we know that the absolute value of the own-price elasticity of sneakers is:

  • 0.4
The own-price elasticity of demand for apples is -1.2. If the price of apples falls by 5%, what will happen to the quantity of apples demanded?
  • It will increase 6%

The demand for good X has been estimated by QX d =12 – 3PX + 4PY. Suppose that good X sells at $2 per unit and good Y sells for $1 per unit. Calculate the own price elasticity.

Consider a market characterized by the following demand and supply conditions: PX = 50 – 5QX and PX = 32 + QX. The equilibrium price and quantity are, respectively,
  • $35 and 3 units.
Consider a market characterized by the following demand and supply conditions: PX = 15 – 2QX and PX = 3 + 2QX. The equilibrium price and quantity are, respectively,
  • $9 and 3 units.
