I. Given: = 1100 (2) P Qd Qs = 3P 100 4. Arc Elasticity where P = 250 and P = 200
Initial values are: PM $20000 PG = $1.00 I = $15000 A = $10000 QT 200 -.01PT +.005PM -10PG +.011 +.003A This function is: 1.(a). Use the above to calculate the arc price elasticity of demand between Pr = $20000 decreasing to PT = $10000. AQ P₁ + P₂ The arc elasticity formula is:Ep ΔΡ Q₁ +2₂ (b). Judging from the computation in (1a), do you expect the revenue resulting from the price decrease to $10000 to increase, remain the same, or decrease relative to the revenue at the price of $20000? (Hint: see the table on page 65 of Truett). Explain your choice. 2.(a) Calculate the point price elasticity of demand for Toyotas at PT= $20000 (which should make Q₁ = 270). Other variables and their values are given at the top, before question #1. The formula is: dQT PT Ep = ● арт LT (b). Does this elasticity indicate that Toyota demand is relatively responsive to changes in Toyota price? Explain why or why not. 3.(a).

The 24-Hour Mart operates a chain of supermarkets. Its best-selling soft drink is Fruitslice. Demand (D) in April for Fruitslice at its Regina supermarket is estimated to be 7,200 cases (24 cans in each case). In March, the Regina supermarket estimated the ordering costs per purchase order (P) for Fruitslice to be $36. The carrying costs (C) of each case of Fruitslice in inventory for a month were estimated to be $1.20. At the end of March, the Regina 24-Hour Mart reestimated its carrying costs to be 1.80 per case per month to take into account an increase in warehouse-related costs. (Click the icon to view additional information.) Requirements 1. Calculate the economic order quantity in April for Fruitslice. Use the EOQ model, and assume in turn that a. D=7,200; P= $36; C = $1.20 b. D=7,200; P= $36; C = 1.80 c. D=7,200; P= $6; C = 1.80 2. How does your answer to requirement 1 give insight into the retailer's movement toward JIT purchasing policies?
