Answer: (1) 700 pizzas

(2) Its revenue increases by $2600.

Explanation:

Given that,

price elasticity of demand for his pizza = -4

Percentage change in price = 10%

Initial Quantity,Q_{0} = 500 Pizzas

Elasticity of demand = \frac{Percentage\ change\ in\ quantity }{Percentage\ change\ in\ price }

-4 = \frac{Percentage\ change\ in\ quantity }{0.1 }

\frac{Percentage\ change\ in\ quantity } = -4 × 0.1

\frac{Q_{1}-Q_{0}}{Q_{0}} = 0.4

\frac{Q_{1}-500}{500} = 0.4

∴ Q_{1} = 700

Initial price, P_{0} = $20

Changed price, P_{1} = $18

Revenue at t = 0

P_{0} Q_{0} = 500 × 20 =$10000

Revenue at t = 1

P_{1} Q_{1} = 700 × 18 = $12600

Therefore, from the above calculations it was seen that his revenue increases by ($12600 - $10000)= $2600 and its sales increases to 700.

Answer:

It is true that raising gasoline prices (either by producing less of it, or by adding taxes) would reduce gasoline use. The concept of price elasticity of demand can helps us explain why.

Explanation:

A good can be either elastic or inelastic depending on its price elasticity of demand. A price elasticity of demand of less than 1 is considered inelastic, while a price elasticity of demand higher than 1 is considered elastic.

Elastic goods are those whose quantity demanded falls or rises more than the price. Inelastic goods are those whose quantity demanded falls or rises less than the price.

Gasoline is a inelastic good in the short-term because even with a price hike, most people will still buy gasoline because they need to move around. However, in the long-term, gasoline becomes more elastic because people replace their buy electric cars, or cars that use less fuel, etc.

What this tells us is that raising gasoline prices can reduce gasoline use in the long-term.

A built-in injustice in this measure is that it affects the poor disproportionally. Poor people also need cars to get around, and a rise in the gasoline price means that they have less money for other basic needs.

suter [353]

Answer:

Ethics

Explanation:

Ethics also called moral philosophy involves how an individual systemises, defends and recommends the concept of right or wrong.

Summer is facing an ethical decision of either returning the bag or keeping it for herself. Her decision will be based on her definition of right or wrong.

If her moral philosophy is one that does not see theft as something that is wrong, she will decide to keep the bag. If on the other hand she sees keeping the bag that is not her own as wrong she will decide to return it.
