A taco hut is trying to determine its demand if it changes it's price. In 2019, they sold tacos for 1.00 and sold 6,000. In 2020, they increase the price of tacos to 1.50 and demand dropped to 5,500. In 2021, the owners of the taco hut want to increase taco price to 2.00 dollars. What would demand be for 2021? What if they lowered the price to .50, how much would demand be?

When the price of a good is $6, the quantity demanded is 50 units per month; when the price is $8, the quantity demanded is 30 units per month. Find the arc price elasticity of demand for this good and comment on it.
