A. price inelastic
B. price elastic
C. unit elastic

Answer 1

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
