The marketing research department of a large manufacturing company has determined that the demand equations for two major items it produces are given by p 2,000-5x+8y and q= 4,000 + 9x-7y where p is the price of item A, q is the price of item B, x is the monthly demand for item A, and y is the monthly demand for item B. Find the total monthly revenue from items A and B when x = 15 and y = 5. A. $29,415 B. $49,975 C. $20,565 D. $50,195

Question #2 Consider the following demand function for frozen dinners where QD is the quantity of frozen dinners demanded per week, P is the price per frozen dinner, PF is the price per fast food meal, Y is the average yearly consumer income, and A is the number of advertisements for frozen dinners.    Demand Function for Frozen Dinners: QD = 1,000 – 10P + 20PF – 0.01Y + A         Suppose that a frozen dinner sells for $4, a fast food meal sells for $6, average yearly consumer income is $50,000, and that there are 20 advertisements for frozen dinners. Calculate and interpret the income elasticity of demand. Calculate and interpret the cross-price elasticity of demand with respect to fast food meals.

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 manager of a bicycle shop has found that, at a price (in Rands) of p(x) = 150 –x/4 per bicycle, x bicycles will be sold . Answer the following:• Find an expression for the total revenue from the sale of x bicycles. (Hint: Revenue = Demand *Price. )• Find the expression for the quantity to be sold q if the demand function demand is given byp = -10q + 3200• What is the number of bicycles x, sold if the price is R40

The demand function for product is p = -4q+400 and the average cost for producing q units 500 is c = 37q + 40 + where p= price, and q= quantity demand. 2 9 1. 2. 3. 4. Compute the point elasticity of demand and find the intervals where the demand is inelastic, elastic, and the price for which the demand is unit elastic. Find the quantity that maximizes the total revenue and the corresponding price. Interpret your result. Find the quantity that minimizes the average cost function and the corresponding price. Interpret your results. What are the quantity and the price that maximize the profit? What is the maximum profit? Interpret your result.

The demand functions for a pineapple is given by p=-0.10x+15.  a.) find the revenue function b.) how many pineapples will you sell when you are maximizing revenue? c.) what price gives the maximum revenue and what is the maximum revenue?

4. An economic consultant provides a firm's marketing manager with the following estimate of the demand function for the firm's product: Qx = 1240 – 3.13Px - 0.611P, + 2.01M + 0.30AX Px = the price of the firm's product per unit; Py = the price of another good per unit; M = money income for the average consumer; Ax = advertising costs for the firm's product. The demand function shown above indicates that: A. The firm's good (X) and the other good (Y) are substitutes and that X is an inferior good B. The firm's good (X) and the other good (Y) are complements and that X is an inferior good C. The firm's good (X) and the other good (Y) are substitutes and that X is a normal good D. The firm's good (X) and the other good (Y) are complements and that X is a normal good

What is the total revenue in a market with the following demand and supply curves? QD=478-6P and QS=128+8P

The market research department of the Better Baby Buggy Co. predicts that the demand equation for its buggies is given by  q = −2.5p + 500  where q is the number of buggies it can sell in a month if the price is $p per buggy. At what price (in dollars) should it sell the buggies to get the largest revenue? p = $

one demand function is linear and the other is called a constant elasticity demand function. Using data tables, show that the price elasticity in the linear demand function is not constant in price, and show that the price elasticity is constant in the constant elasticity demand function.
