Thesuccessful bid for the construction materials in the first home is $64,800, or $27 per square foot.The purchasing manager believes that several actions can be taken to reduce material costs by8% each time the number of homes constructed doubles. Based on this information,a. What is the estimated cumulative average material cost per square foot for the first fivehomes?b. What is the estimated material cost per square foot for the last (16th) home?able 4-4 on page 197 shows a relation called GRADE REPORT for a university. Your assignment is as follows: Draw a relational schema and diagram the functional dependencies in the relation. In what normal form is this relation? Decompose GRADE REPORT into a set of 3NF relations. Draw a relational schema for your 3NF relations and show the referential integrity constraints (as shown in Figure 4-5 on page 163). Draw an ER-diagram for your answer to part d above.The Build-Em-Fast Company has agreed to supply its best customer with three widgets during each of the next 3 weeks, even though producing them will require some overtime work. The relevant production data are as follows: Week Maximum Production, Regular Time Maximum Production, Overtime Production Cost per Unit, Regular Time 1 2 2 $300 2 3 2 $500 3 1 2 $400 The cost per unit produced with overtime for each week is $100 more than for regular time. The cost of storage is $50 per unit for each week it is stored. There is already an inventory of two widgets on hand currently, but the company does not want to retain any widgets in inventory after the 3 weeks. Management wants to know how many units should be produced in each week to minimize the total cost of meeting the delivery schedule. Formulate this problem as a transportation problem by constructing the appropriate parameter table.
