When sold for $260,000.00, Ferraris have an annual supply of 6431 vehicles and an annual demand of 6518 vehicles. When their price increases to $276,000.00, the annual supply increases to 6907, and the demand decreases to 5886 billion gallons. (a) Assuming that the supply and demand equations are linear, find the supply and demand equations. Supply Equation p = Demand Equation p = (Note: The equations should be in the form p = mq + b where p denotes the price (in dollars) and q denotes the quantity. The slope and y-intercept should be accurate to two decimal places). (b) Find the Equilibrium price and quantity. Equilibrium price p = Equilibrium quantity q = (Note: The equilibrium price and quantity should be accurate to two decimal places, and the equilibrium price should include a dollar sign).
Which one of the following descriptions is CORRECT?
A company produces and sells a consumer product and is able to control the demand by varying the selling price. The approximate relationship between price and demand is 2700 5000 p = 38 + (for D>1) D² The company is seeking to maximize its profit. The fixed cost is $1,000 and the variable cost is $ 40 per unit. What is the number of units and total amount that should be produced and sold each month to maximize profit?
(a) The new PlayBox gaming consoles retail for $900 each. However, a shortage of consoles caused by manufacturing delays and parts supply issues have lead to scalpers purchasing large numbers of consoles and reselling them for a profit. Due to a manufacturing fault, the scalper incurs a 50% loss on six consoles. i) If the scalper normally makes a 40% profit on the consoles, how many consoles must they sell to make up for their loss? ii) The scalper is impatient and decides to increase their price to make up for the loss faster. What price must they resell the consoles at to make back their loss upon the sale of their fourth console at the increased price?
A large company in the communication and publishing industry has quantified the relationship between the price of one of its products and the demand for this product as Price=160−0.02×Demand for an annual printing of this particular product. The fixed costs per year (i.e., per printing)=$47,000 and the variable cost per unit=$40. What is the maximum profit that can be achieved? What is the unit price at this point of optimal demand? Demand is not expected to be more than 4,000 units per year. The maximum profit that can be achieved is $? (Round to the nearest dollar.) The unit price at the point of optimal demand is $? per unit.
Q)Vegemite has been recently introduced to the Chinese market. It sells for the equivalent of $2 per jar, and costs $0.50 per jar to make. The company’s fixed costs are $20,000. How many jars of vegemite need to be sold to break even?
An electronics company makes communications devices for military contracts. The company just completed a large contract. The Army contract was for 6808 devices that were produced by 43 workers in three weeks. Each worker worked 40 hours per week. What was the prductivity for the ARMY contact in devices per labour hour? (State your answer rounded to two decimal places)
A company has established that the relationship between the sales price for one of its products and the quantity sold per month is approximately p = 75 – 0.1D units (D is the demand or quantity sold per month and p is the price in dollars). The fixed cost is $1,000 per month and the variable cost is $30 per unit produced. Solve, a. What is the maximum profit per month related to thisproduct? b. What is the range of profitable demand during a month?
The state of New Jersey has in circulation (as of 2011) an instant lottery game called $1,000 Downpour. The cost of each ticket for this lottery game is $5.00. A player can instantly win $75,000, $1,000, $100, $50, $20, $10, or $5. Each ticket has 19 spots covered by latex coating, and the top four spots contain numbers that, if matched by the player's numbers, win money. The remaining 15 spots belong to the player. A player wins if any of the numbers in the player's 15 spots matches any of the four winning numbers. Number of tickets that can win Prizes 0 (i.e. not a winner) 2,853,533 621,075 10 327,600 20 58,500 50 31,200 100 5525 1,000 2561 75,000 6. Total= 3,900,000 tickets sold Find and interpret the expected outcome of this game. [Write your answer as a complete sentence]
You have been hired as a marketing consultant to Johannesburg Burger Supply, Inc., and you wish to come up with a unit price for its hamburgers in order to maximize its weekly revenue. To make life as simple as possible, you assume that the demand equation for Johannesburg hamburgers is linear. (a) Your market studies reveal the following sales figures: When the price is set at $2.00 per hamburger, the sales amount to 6000 per week, but when the price is set at $4.00 per hamburger, the sales drop to zero. Use these data to find the linear demand function q(p), where p is the price per hamburger and q is the number of hamburgers they sell at that price per week. q(p) = (b) Find the price elasticity of demand. E(p) = (c) When you raise the price by 1% from $2 per hamburger, the demand decreases Demand is of unit elasticity. v by X %.

C&A Fast Food has four activities in serving a customer: greet customer, take order, process order, and deliver order. Each activity is staffed by one employee (for a total of four employees). The processing time for each activity is given as follows: Greet customer Take order Process order Deliver order Activity Processing time per customer 2 seconds 30 seconds 60 seconds 5 seconds Assume demand is unlimited. If one additional employee is added to the bottleneck activity, what will be the percentage change in process capacity?
