Textbook Question
Chapter 5, Problem 3.1P
[Related to the Economics in Practice on p. 99] At Frank’s Delicatessen, Frank noticed that the elasticity of customers differed in the short and longer term. Frank also noticed that his increase in the price of sandwiches had other effects on his store. In particular, the number of sodas sold declined while the number of yogurts sold went up. How might you explain this pattern?

From the economics information below Answer This QUESTION :
what is the degree of price elasticity of demand os Starbucks ? and why ?
In January 2020, Starbucks raised their beverage prices by an average of1% across the U.S, a move that represented the company’s firstsignificant price increase in 18 months. I failed to notice because the pricechange didn’t affect grande or venti (medium and large) brewed coffeesand I don’t mess with smaller sizes, but anyone who purchases tall size(small) brews saw as much as a 10 cent increase. The company’s thirdquarter revenue rose 25% to $417.8 million from $333.1 million a yearearlier, and green coffee prices have plummeted, so what gives?Starbucks claims the price increase is due to rising labor and non-coffeecommodity costs, but with the significantly lower coffee costs alreadyimproving their profit margins, it seems unlikely this justification is the truereason for the hike in prices. In addition, the price hike was applied to lessthan a…
I need the computation for this one, not an explanation. Thank you
You start a business making decorative reusable water bottles.
Suppose the demand for the bottles is modeled by the equation q = V15 – 2p
where p is the price per bottle and q is the number of bottles sold per week.
Suppose that your cost of materials for each bottle is 3 dollars.
a) Calculate the price elasticity of demand when p = 3. Write a sentence
explaining what this means in terms of the demand and the price.
b) Find the range of prices for which demand is inelastic (assume p < 0)
c) Find the price that would maximize your revenue.
d) Find the price that would maximize your profit. (Include steps justifying
that this is a maximum).
