Big City Java is a local coffee bar. Using Excel, the manager of Big City Java estimates the weekly demand function for their grand mocha coffees to be Qd = 650 (15.25 x P). The estimated regression equation suggests that if Big City Java decreased its price of grana mocha coffees from $7.50 to $6.50, the predicted quantity demanded of coffees would O increase by 15.25 O exactly double O not change O decrease by 15.25

- You decide to sell pairs of running shoes. Assume that the quantity demanded is alinear function of the price. It is known that if you charge $40 per pair of shoes, thenyou will be able to sell 400 pairs of shoes in a month. If you charge $60 per pair ofrunning shos, then you can sell 300 pairs of shoes in a month. It is also known thatyour monthly fixed cost is $100 and pairs of shoes cost $20 per shoe to produce. Findwhat price you should charge for a pair of shoes in order to maximize profit in amonthProducers of a certain brand of refrigerator will make 1600 refrigerators available when the unit price is $320. Ata unit price of $370, 5600 refrigerators will be marketed. Find the equation relating the unit price p of a refrigerator to the quantity supplied x if the equation is known to be linear How many refrigerators will be marketed when the unit price is s4207 refrigerators What is the lowest price at which a refrigerator will be marketed?The demand equation for a certain brand of pencil is 100y? + 9t2 = 3600 where (y) represents the number (in thousands) of ten-packs demanded each week when the unit price is $(t). How fast is the quantity demanded increasing when the unit price per ten-pack is $14 and the selling price is dropping at the rate of $0.15 per ten-pack per week?
- An analyst for FoodMax estimates that the demand for its “Brand X" potato chips is given by: InQx = 10.34 – 3.2 In Px+ 4Py+ 1.5 In Ax where Qx and Px are the respective quantity and price of a four-ounce bag of Brand X potato chips, Pyis the price of a six-ounce bag sold by its only competitor, and Ax is FoodMax's level of advertising on brand X potato chips. Last year, FoodMax sold 5 million bags of Brand X chips and spent $0.25 million on advertising. Its plant lease is $2.5 million (this annual contract includes utilities) and its depreciation charge for capital equipment was $2.5 million; payments to employees (all of whom earn annual salaries) were $0.5 million. The only other costs associated with manufacturing and distributing Brand X chips are the costs of raw potatoes, peanut oil, and bags; last year FoodMax spent $2.5 million on these items, which were purchased in competitive input markets. Based on this information, what is the profit-maximizing price for a bag of Brand X…The weekly demand function is given by p+x+4xp = 68, where x is the number of thousands of units demanded weekly and p is in dollars. If the price pis decreasing at a rate of 91 cents per week when the level of demand is 5000 units, which one of the following statements is true? Demand is decreasing at 1330 units per week Demand is decreasing at 1470 units per week Demand is increasing at 1470 units per week O Demand is increasing at 1400 units per week O Demand is decreasing at 1400 units per weekAs the price of bananas fell from $0.60 to $0.40 per pound, the quantity demanded rose from 300 pounds of bananas consumed to 500 pounds of bananas consumed.

- Suppose that daily demand for breakfast sandwiches at a local store is given by the following: Qd = 15-3P 3. As you can see, the price elasticity is different depending on the values of prices at which it is evaluated. For what price is the own price elasticity of demand one? In other words, for what price is demand unit elastic? 4. For what range of prices is demand elastic (\€ (EQ¹,p| > 1) ? For what range of prices is demand inelastic (¹.p< ?Suppose Amazon lowers its Prime membership monthly fee from $12.99 to $9.99. The price elasticity of demand for Amazon membership subscription in this price range is estimated at -0.8. You predict that the number of Prime subscriptions will (increase/decrease) increase Aby (enter a number rounded to one digit after the decimal point, e.g., 22.2) A/ % and that Amazon's revenue will (increase/decrease) A by (enter a number rounded to one digit after the decimal point, e.g., 9.9) A %.Given the demand function D(p) = 375 – 3p², Find the Elasticity of Demand at a price of $1 At this price, we would say the demand is: O Unitary O Inelastic O Elastic Based on this, to increase revenue we should: Keep Prices Unchanged O Lower Prices Raise Prices
