The Marginal Revenue function for a company's product is:

MR = 240000 - 22x

where x equals the number of units sold. If total revenue equals 0 when 0 units are sold, determine the total revenue.

The supply and demand functions for a product are 𝑞𝑠 = 𝑝 2 − 300 𝑎𝑛𝑑 𝑞𝑑 = 𝑝 2 − 30𝑝 + 2200 . Determine the market equilibrium price and quantity.

You are planning on throwing a party after social distancing is lifted. A cube-shaped tank has edges that are choose a whole number between 11 in and 14 in. ___________ long. The tank is filled with punch that has a density of 0.02 lb./in³. 

It is known that pancake sales at an athletics meeting between a number of schools follow the following pattern: when the price is R3,00 per pancake, 3 000 pancakes are sold during the day and when the price is R2,50 each, 5 000 are sold. Find the demand function with quantity, Q, as a function of price, P. [1] Q = −4P + 15 [2] Q = −4 000P + 15 000 [3] Q = −1 000P + 6 000 [4] Q = 4 000P − 9 000 

The toy factory produces X cast-iron toy aeroplanes per month at a fixed cost of R25 000. Each aeroplane costs R15 to produce and it is sold for R45 each. The total cost and profit functions are [1] T C = 15X + 25 000; π = 30X − 25 000. [2] T C = 45X + 25 000; π = 30X − 25 000. [3] T C = 45X; π = 60X − 25 000. [4] T C = 25 000 + 15X; π = 30X + 25 000.

[1] Line BD represents the supply function and there is no demand line. [2] Both lines (1)and (2) represent supply functions and there is no demand line. [3] Line (1) represents the demand function and line (2) the supply function. [4] Line (1) represents the supply function and line (2) the demand function. Question 12 Which of the following statements is true? [1] Point D is the break-even point. [2] Point C represents the price that no consumers will accept. [3] The area of triangle ABD represents the consumer surplus at equilibrium. [4] The area of triangle ACD represents the producer surplus at equilibrium.

Which one of the following statements is true? Price elasticity of demand measures [1] changes in a product’s price. [2] sensitivity of quantity demanded to change in price. [3] percentage change in quantity demanded. [4] the relationship between price and quantity demanded.

The demand function of a product is given as P = 70 − 3Q, where P and Q are the price and quantity, respectively. Determine the price elasticity of demand if the price is equal to P = 10. [1] −1,167 [2] −0,960 [3] −0,800 [4] −0,167
