- Sally runs a vegetable stand. The following table shows two points on the demand curve for the heirloom tomatoes she sells: Price $3.50 $2.25 Quantity demanded per week 150,000 250,000 Sally's marginal revenue from lowering the price of tomatoes from $3.50 to $2.25 is $ 0.375. (Enter your response rounded to two decimal places.) Lowering the price from $3.50 to $2.25 results in an output effect of $ and a price effect of $.

- Attempts Average: /3 3. The components of marginal revenue Gilberto's Fire Engines is the sole seller of fire engines in the fictional country of Pyrotania. Initially, Gilberto produced four fire engines, but he has decided to increase production to five fire engines. The following graph shows the demand curve Gilberto faces. As you can see, to sell the additional engine, Gilberto must lower his price from $105,000 to $90,000 per fire engine. Note that while Gilberto gains revenue from the additional engine he sells, he also loses revenue from the initial four engines because he sells them all at the lower price. Use the purple rectangle (diamond symbols) to shade the area representing the revenue lost from the initial four engines by selling at $90,000 rather than $105,000. Then use the green rectangle (triangle symbols) to shade the area representing the revenue gained from selling an additional engine at $90,000.

- what is the profit-maximizing output quantity?arrow_forwardQuestions 1-3 use the following case to determine a way to take a single product, like toilet and bundle it in such a way as to extract all of the profit at the time of the initial sale. You go to CostCo or Walmart and you see paper towel sold in a bundle and you wonder how the retailer can make any money. You do a little research and you find that the demand for paper towels is depicted by the following demand curve and marginal cost: P-$2.20 (1/10)*Q MR-$2.20 (2/10) Q МС 0.20 where P is the price of paper towels, MC is the marginal cost of paper towels, MR is the marginal revenue of paper towels and Q is the quantity of paper towels. So you decide to try two different pricing strategies: 1) sell one roll at a time and 2) use multi-part pricing to sell a bundle. For pricing strategy two, you determine that the quantity, price and profit are: Q 20, P $24.0, Profit $20 Q 10, P 1.20, Profit 10 Q 20, P $0.20, Profit 0 = Q 10, P $4.0, Profit $38 a.
