Patty bakes pies, she sells them for $10 each and sells about 55 pies per week. But the price of her ingredients increased so she' s contemplating a price increase. She will raise the price to $12 and she estimates her demand will fall to 50 pies per week. Calculate the elasticity coefficient for Patty's Pies. Are Patty's Pies elastic or inelastic? Should she raise her prices? Or keep them the same? You should be able to show your work.arrow_forward
- Congratulations! You have just landed your first job out of college as an economic analyst at the Bureau of Labor Statistics. Your starting salary is $55,000 per year; an increase of 250% per year over the salary you made at the local coffee shop. The corresponding table gives the percentage change in your purchases of each good after your income increases. Use this information to estimate your income elasticity of demand for each of the items.arrow_forwardThe subway fare in your town has just been increased from 50 cents to $1.00 per ride.

Suppose a company sold 1000 replica Eames chairs for a price of $600 each. However, when they set the price at $750, they only sold 750. Which of the following statements are true: The point price elasticity of demand for replica Eames chairs at a price of $600 is unit elastic. At a price of $600 per chair, a 1% increase in the price of replica Eames chairs would lead to a 1% decrease in the quantity of chairs sold. The point price elasticity of demand for replica Eames chairs at a price of $600 is 0.0239 (to four decimal places). The point price elasticity of demand for replica Eames chairs at a price of $600 is 0.02 (to two decimal places).arrow_forward
- Each scenario gives some information about price elasticity of demand. For each, calculate the missing data, and determine if the price change under consideration will increase, decrease, or not change the firm's total revenue. Honest Abe's Used Cars estimates the price elasticity of demand for their cars to be -4.1. Last month, Abe tried a new marketing scheme which decreased the number of cars sold by 87%. Abe must have his prices by -27.87 Abe's total revenue by increased and total revenue to increased. At Webs-R-Us, a website design company, the new manager has decided to increase the price of Webs-R-Us services by 15%. She estimates that Webs-R-Us has a price elasticity of demand at -0.30. The manager expects the number of websites designed to decrease increase. %. e %arrow_forwardA firm estimates its price elasticity of demand for poutine to be -2 and its elasticity of demand with respect to advertising to be 0.1. The firm currently charges $10 and sells 10,000 units. What will lead to a larger increase in revenue: a $2 drop in price (while keeping advertising constant) or doubling the amount of advertising (while keeping the price constant)?arrow_forwardMacmillan Learning You have been appointed head of marketing for Barry's Younique Yachts. Barry, the CEO, is interested in determining whether offering his yachts at a lower price would increase the firm's revenue. He asks you for advice. Using your knowledge of elasticity, you should tell Barry that he should increase his prices. Demand for yachts is perfectly inelastic, so a price increase will cause total revenue to increase. that he should reduce his prices. Yachts are luxury goods and therefore exhibit a high price elasticity of demand. Thus, reducing prices would increase revenue. that he should increase his prices. Demand for yachts is likely to be elastic because they are so much fun to drive. Thus, increasing prices would increase revenue. that he should reduce his prices. Yachts are a necessity and therefore have a low price elasticity of demand. Thus, reducing prices would increase revenue.arrow_forward
