Using the high-low method, separate each mixed expense into variable and fixed elements. Express the variable and fixed portions of each mixed expense in the form Y= a + bx. Note: Round the Variable cost per unit to 2 decimal places. Shipping expense Salaries and commissions expense Variable Cost per unit per unit Fixed Cost Y = Y = Formula + X X

2. FIFO 3. LIFO 4. Weighted average method (Round average unit cost to the nearest cent, and round all other calculations and your final answers to the nearest dollar.)

I need number 3. Compute the gross margin for FIFO method and LIFO method.

Direction: Read carefully and answer the questions below. Encircle the letter of the correct answer. 1. Which of the following is an example of a variable cost? а. interest b. ingredients с. insurance d. lease 2. What type of cost varies depending on the quantity of products being produced? а. fixed b. net sales с. total d. variable 3. Which among the following concepts is usually seen on the top item in an income statement from which all costs and expenses is subtracted to arrive at net income? a. fixed cost b. net sales с. total cost d. variable cost 4. When do we obtain the break-even point? When the fixed cost is equal to the total cost When the total cost is equal to the variable cost When the variable cost is equal to the fixed cost d. When the number of units of goods sold covers the all the costs а. b. с. 5. Which of the following is NOT true? а. The fixed cost does not vary over time. b. The total cost is the sum of the fixed cost and the variable cost. с. The total cost is…

Unit cost is the same as average cost of a product or service OA. True O B. False

d.    Perpetual system, LIFO cost flow. e.    Periodic system, weighted-average cost flow. f.    Perpetual system, moving-average cost flow.

Find the marginal profit function if cost and revenue are given by C(x) = 224 + 0.8x and R(x) = 8x – 0.05x2. P'(x) =D

Find the marginal profit function if cost and revenue are given by C(x) = 223 +0.7x and R(x) = 6x -0.09x² P'(x)=

Which of the following summarizes the weighted average cost flow assumption? Weighted average assumes that costs flow in the reverse order incurred. O Weighted average assumes that cost flow is allocated by the physical weight of items purchased. O Weighted average assumes that costs flow at an average of the costs available. O Weighted average assumes that costs flow in the order incurred.

In the cost behavior equation, b*X denotes the variable cost per unit. Select one: O True O False
