5.19 explain. ### 5.19. T-MobileIt is estimated that, if T-Mobile were to increase the price of its basic plan by 10 percent, demand would decline by 20 percent. What is the value of the price elasticity of demand? Suppose that T-Mobile’s current margin (price minus unit variable cost divided by price) is equal to 25 percent. What should T-Mobile do: increase price, decrease price, or keep it constant?In this scenario, the problem provides enough information to explore the concept of price elasticity of demand, which is a measure of how sensitive the quantity demanded of a good is to a change in price. #### Key Concepts:- **Price Elasticity of Demand (PED):** This can be calculated using the formula: \[ \text{PED} = \frac{\%\text{ Change in Quantity Demanded}}{\%\text{ Change in Price}} \] - **Calculation:** - Percentage change in price = 10% - Percentage change in demand = -20% - Therefore, the PED = (-20% / 10%) = -2A PED value of -2 indicates that the demand is elastic, meaning consumers are relatively responsive to price changes in T-Mobile’s basic plan.#### Decision-Making:- **T-Mobile’s Margin:** The problem statement mentions a margin of 25%. Given the elasticity, if T-Mobile increases prices, the higher sensitivity causes a proportionally larger drop in demand, impacting total revenue.- **Recommendations:** - Since the demand is elastic ($PED < -1$), increasing the price would lead to a decrease in total revenue. - It may be advisable for T-Mobile to lower the price or adjust strategies to increase demand while maintaining or increasing revenue, considering the impact on profit margins. This exercise allows students to apply economic principles to real-world business decisions, emphasizing the importance of understanding consumer behavior and market dynamics.

ONLY ANSWER QUESTION #2 1. Online the timing and tailoring of prices to specific models of products is the key to successful pricing in online markets. And “Thanks to the ready availability of data in online markets, a pricing manager can easily approximate the elasticity of demands for the different products it sells online.”Assuming a 10 percent decrease in price increases sales by 28 percent, calculate the price elasticity of demand? If the wholesale price of the online product is $50 and sells at a price comparison site that charges $.50 per click and boasts a conversion rate of 5 percent (an average of 20 clicks are needed to generate a sale). What price should you charge for the product? What is the optimal markup on cost? 2. The authors assert that price sensitivity is affected by (1) product life cycles, and (2) numbers of competitors.

Harding Enterprises has developed a new product called the “Quest Simulator (QS)”. The market demand for this product is given as follows: Q = 240 - 4P. If QS is priced at $40, what is the point price elasticity of demand? Is demand elastic or inelastic? What is the maximum amount that consumers are willing to pay for the quantity demanded at the price of $40?

In this question, you'll have to solve for price elasticity of demand using the percent change formula. When the old price of a food package was $4.64 per package, the old quantity was 1,081 packages were sold each day. After the price increased to the new price $10.89 per package, sales dropped to a new quantity of 447 packages per day. Using these numbers, what is the price elasticity of demand for food packages? Round your answer to 3 decimal places.
Suppose you are advising an industry association on the predicted effects of a price change on quantity demanded and total expenditure on its product. The current price is $1.20 per unit, and quantity demanded is 2500 units per day. Based on extensive empirical studies, you know that price elasticity of demand for the product is 0.7. If the price increases to $2.20 per unit, what is the predicted percentage change in quantity demanded? Will total expenditure increase or decrease? (Remember to use the averaging method to calculate the percentage change in price.) The predicted percentage change in quantity demanded is%. (Enter your response rounded to the nearest integer. Do not include a negative sign in your response.) Will total expenditure increase or decrease? Total expenditure is related with price because the price elasticity of demand is Question Viewer so total expenditure will 1
