Answer:
Explanation:
price elasticity of demand = percentage change in quantity demanded / percentage change in price
revenue = price x quantity
if price decreased by 30% and total revenue decreased by 35%, then PED is inelastic
a will show you in an example
original price = $10
original quantity = 100
if PED was unit elastic
= 30% / -30% = -1, sales volume increased by 30%
total revenue went form $1,000 to $910
if PED was elastic
= 50% / -30% = -1.7, sales volume increased by more than 30%, lets say 50%
total revenue went from $1,000 to $1,050
if PEd was inelastic
= 10% / -30% = -0.33, sales volume increased by less that 30%, lets say 10%
total revenue went from $1,000 to $770
the more inelastic, the larger the decrease in total revenue
