The Squish, an upscale $150-$seat restaurant, revises its menu every six months. The revisions are

based, in part, on the price elasticity of demand for their menu items. During the thirty$-$day periods

before and after the last menu revision, the selling prices and quantity sold of three items were as

follows:

Item Prior to revision After revision

Price Quantity Price Quantity

Super Burger $$4\mathrm{.}95450$ $$5\mathrm{.}45400$

Golden Chicken $$6\mathrm{.}45800$ $$5\mathrm{.}951,000$

Ocean Delight $$6\mathrm{.}45600$ $$6\mathrm{.}95400$

The above sales quantities have remained fairly constant each month since the last menu revision.

Q$1$: Compute the price elasticity of demand for each menu item.

Q$2$: Advise Kay Rae, the manager, of the implications of your results for each menu item.
