Solve the system of linear equations using the Gauss-Jordan elimination method. (If there is no solution, enter NO SOLUTION. If there are infinitely many solutions, express your answer in terms of the parameter t. Use s if a second parameter is needed.) 3x โˆ’ 2y + 4z = 142x โˆ’ 4y + 5z = โˆ’2x + 2y โˆ’ z = 11 (x, y, z) =

PROBLEM 5-29 Changes in Cost Structure; Break-Even Analysis; Operating Leverage; Margin of Safety LO5-3, ใ„ดใ…ˆ LO5-4, ์ง€ LO5-5, ๋‹ˆ LO5-7 Morton Company's contribution format income statement for last month is given below: The industry in which Morton Company operates is quite sensitive to cyclical movements in the economy. Thus, profits vary considerably from year to year according to general economic conditions. The company has a large amount of unused capacity and is studying ways of improving profits. Page 234 Required: New equipment has come onto the market that would allow Morton Company to automate a portion of its operations. Variable expenses would be reduced by $9 per unit. However, fixed expenses would increase to a total of $225,000 each month. Prepare two contribution format income statements, one showing present operations and one showing how operations would appear if the new equipment is purchased. Show an Amount column, a Per Unit column, and a Percent column on each statement. Do not show percentages for the fixed expenses. Refer to the income statements in (1). For the present operations and the proposed new operations, compute (a) the degree of operating leverage, (b) the break-even point in dollar sales, and (c) the margin of safety in dollars and the margin of safety percentage. Refer again to the data in (1). As a manager, what factor would be critical in deciding whether to purchase the new equipment? (Assume enough funds are available to make the purchase.) Refer to the original data. Rather than purchase new equipment, the marketing manager argues the company's marketing strategy should be changed. Rather than pay sales commissions, which are currently included in variable expenses, the company would pay salespersons fixed salaries and would invest heavily in advertising. The marketing manager claims this new approach would increase unit sales by 30% without any change in selling price; the company's new monthly fixed expenses would be $180,000; and its net operating income would increase by 20%. Compute the company's break-even point in dollar sales under the new marketing strategy. Do you support the marketing manager's proposal?

Directions: A small tie shop finds that at a sales level of $x$ ties per day, its marginal profit is $P'(x)$ dollars per tie, where $P'(x)$ is given below Also, the shop will lose $80 per day at a sales level of $x = 0$. $P'(x) = 1.8 + 0.05x - 0.0012x^2$ Find the profit $P(x)$ from operating the shop at a sales level of $x$ ties per day. $P(x) = $ Hint: You need to find a value for $+C$. What should the profit $P(x)$ be, at a sales level of $x = 0$?

1. Assuming motion along a line so that direction is indicated by a positive or negative sign. Based on the definitions of position, velocity and acceleration do the following; On a graph of position versus time draw and label curves that represent the motion of an object with zero constant velocity, a positive constant velocity, a negative constant velocity, an initial positive velocity with constant positive acceleration, an initial positive velocity with constant negative acceleration, an initial negative velocity with constant positive acceleration and an intial negative velocity with constant negative acceleration (the choice of initial position is up to you, also if one graph would be too crowded, use more than one graph). On a graph of velocity versus time draw and label curves that represent zero constant velocity, constant positive velocity, constant negative velocity, an initial positive velocity and constant positive acceleration, an initial positive velocity and constant negative acceleration, an initial negative velocity and constant positive acceleration, an initial negative velocity and constant negative acceleration, zero initial velocity and constant positive acceleration and zero initial velocity and constant negative acceleration. 2. Can the average velocity be greater than the average speed? If so, why? If not, why not? 3. What is required for the average speed to be greater than the magnitude of the average velocity? Give an example. 4. If you travel at a constant 20 m/s for 5 minutes and then travel at a constant 10 m/s for an additional 5 minutes, is your average speed for the 10 minutes 15 m/s? On the other hand, if you travel at a constant 20 m/s for a distance of 5000 meters and then travel at a constant 10 m/s for an additional 5000 meters, is your average speed for the 10000 meters 15 m/s? Why should the two answer be different?
