Suppose the demand for a product is given by QD=100-5P, where QD is quantity per year measured in kilogram and P is the price in AUD per kilogram. The supply curve for this product is given by QS=4P-8. b) Calculate the elasticity of demand and supply at the equilibrium price.

The price of a good decreased from $35 to $15. The initial quantity demanded is 240 Assuming a demand curve with constant unitary price elasticity, calculate the quantity demanded at a price of $15. Use the midpoint method.

Calculate price elasticity of demand if quantity demanded of a commodity rises from 800 units to 850 when price falls from Rs. 20 per unit to Rs. 19 per unit.

Suppose that the price per unit p as a function of the demanda is p = 478.8 -0.9x. (a) Calculate the price elasticity of demand when x = 132. n = -2.44, therefore the demand is elastic (b) Calculate the price elasticity of demand when x = 425. n = -0.202 therefore the demand is inelastic (c) Find the demand that gives unit elasticity. x = 266.0 ✓

The table below gives part of the supply schedule for personal computers in the United States. Price Quantity Supplied before tech change $1,100 12,000 $900 8,000 a) Calculate the price elasticity of supply when price rises from $900 to $1,100 using the arc elasticity formula (the midpoint method).  b)  Now suppose that technology changes such that at every price, 1000 more computers are supplied.   Now, as prices rise from $900 to $1,100, is the elasticity of supply smaller than, larger than, or equal to the elasticity in part a)? Price Quantity Supplied after tech change $1,100 13,000 $900 9,000 c) Does the change in b) change the slope of the supply curve? Are slope and elasticity the same thing? Explain.

3. Consider the function y = 2x2 + x for which dy/dx = 4x + 1. Calculate the elasticity of y with respect to x at x = 2.

What is the formula for measuring the price elasticity of supply? Es = (Click to select)percentage change in quantity supplied / percentage change in pricepercentage change in quantity demanded / percentage change in incomepercentage change in quantity demanded / percentage change in price Suppose the price of apples goes up from $20 to $23 a box. In direct response, Goldsboro Farms supplies 1300 boxes of apples instead of 1200 boxes. Compute the coefficient of price elasticity (midpoints approach) for Goldsboro’s supply. Instructions: Round your answer to two decimal places. Es = Is its supply elastic, or is it inelastic? Supply is (Click to select)elasticinelastic.

Calculate the elasticity of supply when the price rise is given as 30% and the quantity supplied rises by 10%

PRICE (Dollars per unit) 350 Z 225 175 Y W 50 Demand 0 10 35 45 70 QUANTITY (Units) For each of the regions listed in the following table, use the midpoint method to identify if the demand for this good is elastic, (approximately) unit elastic, or inelastic. Elastic Inelastic Unit Elastic Region Between W and X Between X and Y О О Between Y and Z О О О True or False: The slope of the demand curve is not equal to the value of the price elasticity of demand. True False

When Price is increased from $40 to $42, the Quantity Demanded falls from 50 units to 45 units, while the Quantity Supplied increases from 50 units to 70 units. Use this information to:(i) Calculate the Price Elasticity of Demand and the Price Elasticity of Supply.(ii) Give the name of the Price Elasticity of Demand and explain what the coefficient tells you about the product.(iii) Calculate the Total Revenue when price is $42.
