Answer: Total Revenue is $100 and the price elasticity is 0.4
Explanation: total revenue is computed as Price * Quantity
$0.5 * 200= $100
Elasticity is the degree of responsiveness of quantity demanded to a change in price.
Old price $1
New price $0.5
Old quantity 75
New quantity 200
Formula- % change in quantity demanded / % change in pride
NB change is (old-new)
Change in Qd= (75-200) / 75 =-1.67
Change in price=(1-0.5)/1=0.5
-1.67/0.5= -3.34
The negative is ignored in price elasticity and the answer is 3.34 which means the product is Elastic
