question 62

Multiple Choice

Use Gauss-Jordan row reduction to solve the given system of equations. $$\begin{array} { r } x + y + z + u + v = 13 \\y + z + u + v = 3 \\x + 2 y + 2 z + 2 u + 2 v = 16 \\x - y - z - z + 16 \\x - 2 y - 2 z - 2 u - 2 v = 4\end{array}$$

• A) \(( 8,4 - z - u - v , z , u , v )\) , z, u, v arbitrary
• B) \(( 9,3 - z - u - v , z , u , v )\) , z, u, v arbitrary
• C) \(( 10,3 - z - u - v , z , u , v )\) , z, u, v arbitrary
• D) \(( 6,3 - z - u - v , z , u , v )\) , z, u, v arbitrary
• E) \(( 13,4 - z - u - v , z , u , v )\) , z, u, v arbitrary

Definitions:

Inventory Costing

The process of assigning costs to inventory items based on the method chosen (e.g., FIFO, LIFO, or weighted average) to accurately value the inventory on the balance sheet and match costs to revenues on the income statement.

Perpetual Inventory

An inventory system that updates the quantity and value of inventory after each transaction or event.

Interim Financial Statements

Financial reports covering a period of less than one year, often used to provide a more immediate view of a company's financial health.

Cost Flow Assumption

Refers to the method used by companies to value and manage inventory; common examples include FIFO (First In, First Out), LIFO (Last In, First Out), and average cost.
