Q6. The table below gives the demand schedule for a good. Price level Quantity Demanded 100 40 80 60 60 80 40 Elasticity Total Revenues 20 100 120 a. What are the total revenues at each point? And what is the elasticity at from 100 to 80 and 80 to 60 and 60 to 40 price levels? b. Draw the demand and total revenues curves. And show the price level to get the maximum total revenues on the graph.

15.  Use the graph to answer the question that follows. What is the price elasticity of demand when price increases from $2 to $4? 0.2 0.5 2 3 5

4-6 Suppose that the price of croissants rises from $2 to $3 per unit. Use the mid-point approach to get the elasticity. answer the following The quantity of orange juice purchased falls from 10 million bottles to 5 million bottles. What is the cross-price elasticity of demand between croissants and orange juice? Are they complements or substitutes? The quantity of jelly purchased increases from 10 million jars to 20 million jars. What is What is the cross-price elasticity of demand between croissants and jelly? Are they complements or substitutes?

lesson business math : pls do in the piece paper with a4 paper   Question 4: Given the demand function: ? = 200 − 2? − ?? + 0.1?2 Where P = 10, PA= 15 and Y = 100, find: a. The price elasticity of demand b. The cross-price elasticity of demand; substitute or complementary goods? c. The income elasticity of demand; inferior, normal, or superior goods? Unconstrained Optimization: Profit Maximization   Question 5: A firm is a monopolistic producer of two goods G1 and G2. The prices are related to quantities Q1 and Q2 according to the demand functions. ?1 = 50 − ?1 ?2 = 95 − 3?2 If the total cost function is: ?? = ?12 + 3?1?2 + ?22 Find the values of Q1 and Q2 which maximize π and deduce the corresponding prices. Lagrange Multipliers   Question 6: Use Lagrange multipliers to find the maximum value of: ? = 4?? Subject to the constraint: ? + 2? = 40   Definite Integration: Investment Flow Question 7: If the investment flow is: ?(?) = 9000√? Calculate: a. The capital formation from the end of…
