On Sundays, Fat City Saloon offers a $0.95 hamburger during the football season, $0.50 less than its regular price. Fat City discovers that its total revenue from hamburger sales increases. This reflects the fact that

a. price elasticity of demand within the $0.95 to

$1.45 price range is less than 1.0.

b. price elasticity of demand within the $0.95 to

$1.45 price range is greater than 1.0.

c. price elasticity of demand within the $0.95 to

$1.45 price range is equal to 1.0.

d. Fat City should raise the price of its Sunday hamburgers to further increase its total revenue.

e. the percentage change in quantity demanded of hamburgers had to be less than the percentage change in its price (from the $1.45 regular to the $0.95 special).
