6. Continuous Compounding . Elizabeth Corday , a quality control supervisor or for Surgery Products , Inc ., is concerned about an increase in distribution costs for disposable syringes from $40 to $50 per case over the last five years . Corday feels that setting up a new direct -sales distribution network at a cost of $58.50 per unit may soon be desirable A. Calculate the unit cost growth rate using the constant rate of change model with continuous compounding B. Forecast when unit distribution costs will exceed the current cost of direct -sales distribution 7. Continuous Compounding .Mark Greene , a control supervisor for County General , Inc ., is concerned about an increase in distribution costs per unit from $24.50 to $25 over the last four years . Greene feels that setting up a new direct -sales distribution network at a cost of $27.50 per unit may soon be desirable A. Calculate the unit cost growth rate using the constant rate of change model with continuous compounding B. Forecast when unit distribution costs will exceed the current cost of direct -sales distribution 8. Continuous Compounding . Abby Lockheart , a quality control supervisor for Intensive care , Inc ., is concerned about an increase in distribution costs per unit from $3 to $3.27 over the last three years . Lockheart feels that setting up a new direct -sales distribution network at a cost of $3.56 per unit may soon be desirable A. Calculate the unit cost growth rate using the constant rate of change model with continuous compounding B. Forecast when unit distribution costs will exceed the current cost of direct -sales distribution 9. Sales Forecast Modeling . The change in the quantity of product A demanded in any given week is inversely proportional to the change in sales of product B in the previous week . That is, if sales of B rose by X percent last week , sales of A can be expected to fall by X percent this week . A. Write the equation for next week's sales of A, using the symbols A = sales of Product A, B = sales of Product B, and t = time . Assume there will be no shortages of either product B. Last week 500 units of A and 250 units of B were sold . Two weeks ago , 200 units of Product B were sold . What would you predict the sales of A to be this week ? 10. Sales Forecast Modeling . The change in the quantity of Beta service demanded in any given week is inversely proportional to the change in sales by Alpha in the previous week . That is, if sales of Alpha rose by X percent last week , sales of Beta can be expected to fall by 0.5X percent this week . A. Write the equation for next week's sales of Beta , using the symbols B = sales of Beta
