Answer:
Urgency / Postponement leads to customer inelastic demand of ice melt.
Explanation:
Elasticity of demand is responsive change in demand of good, due to change in price. Formula = % change in demand / % change in price
Factors Affecting Price Elasticity of Demand : Nature of commodity, Income, substitutes availability, time period, urgency / postponement, share in total expenditure,
Inelastic Demand is when demand responds proportionately less to price change. % change in demand < % change in price
Case 'Customer critically needs ice melt to drive to work' : This has inelastic demand i.e demand less respondent to price changes (he will buy that at high price too). Such because of the urgency of this demand & less scope of its postponement.
