Question

Data for the market for graham crackers is shown below.  Calculate the elasticity of demand between the following prices.

Price of crackers

Quantity Demanded (per month)

$3

80

$2.5

120

$2

160

$1.5

200

$1

240

$1.00 - $1.50: ___________________________________

$1.50 - $2.00: ___________________________________

$2.00 - $2.50: ___________________________________

$2.50 - $3.00: ___________________________________

If the price of graham crackers is $2.50 should firms raise or lower their prices if they want to increase revenue?  Explain this in terms of elasticity.  lease show work

Explanation / Answer

elasticity of demand = dq/q / dp/p


$1.00 - $1.50: -40/240 /0.5/1 = -0.333

$1.50 - $2.00: (-40/200) / (0.5/1.5) = -0.6

$2.00 - $2.50: (-40/160)/(0.5/2) = -1

$2.50 - $3.00: (-40/120) / (0.5/2.5) = -1.66


the firm should lower the price as we see the elasticity increases
