A building contractor has accepted orders for 5 type A houses, 7type B houses and 12 type C houses. The contractor is familiar withthe kinds of raw materials that go into each type of house. Theseraw materials are steel, wood, glass, paint and labour. The variousquantities of steel, wood, glass, paint, and hours of labour requiredto build each type of house are identified in appropriate units foreach type by the matrix:steel wood Glass Paint LabourA5B7C2016717181221258513It is known that steel costs GH¢2500 per unit, wood costs GH¢1200per unit, glass costs GH¢800 per unit, paint costs GH¢150 per unit,and labour costs GH¢1500 per hour.(i) What quantity of each type of raw material should he obtain tofulfill his contract?ii) Determine the total cost of raw materials for all the houses hewill build.

6. please help help!! Answer with step by step well explained: On Cybertron, we manufacture Autobots, produce energy and extract metals. • To produce a unit of Autobots, we need 0.6 units of energy and 0.8 units of metals. • To produce a unit of energy, we need 0.1 unit of Autobots, and 0.1 unit of energy. • To produce a unit of metal, we need 0.1 unit of Autobots, 0.2 unit of energy, and 0.1 unit of metals. In a production cycle, we export 6,500 units of Autobots (sent to the Great War) but have to import 4,100 units of energy and 2,000 units of metals (both obtained from other planets). • a) Identify the variables. • b) Give the system of linear equations that connects these variables with the Leontief model. • c) Give the augmented matrix for this problem that will be used to calculate the production levels of the three sectors. • d) Calculate the level of production of the third sector only (here metal).
Active Frame, Inc., manufactures clear and tinted sport glasses. The manufacturing of clear glasses takes 45,000 direct labor hours and involves 1,700 parts and 115 inspections. The manufacturing of tinted glasses takes 115,000 direct labor hours and involves 1,400 parts and 450 inspections. The traditional method applies P560,000 of overhead based on direct labor hours. What is the amount of overhead per direct labor hour applied to the clear glass products?

This is a practice exam. I would like to know how to slove usign excel or megastat Wenton Powersports produces dune buggies. They have three assembly lines, “Razor,” “Blazer,” and “Tracer,” named after the particular dune buggy models produced on those lines. Each assembly line was originally designed using the same target production rate. However, over the years, various changes have been made to the lines. Accordingly, management wishes to determine whether the assembly lines are still operating at the same average hourly production rate. Production data (in dune buggies/hour) for the last eight hours are as follows. (You may find it useful to reference the F table.)
