She Exercise 5-6 Scatter diagram and measurement of cost behavior P1 Use the following information about sales and costs to prepare a scatter disa reflects the behavior displayed by this cost. Determine whether the cost is vari mixed, or curvilinear. Period Sales Period Sales Costs Costs $590 560 $580 320 $760 800 200 400 480 230 240 720 $390 240 230 550 400 390 620 550 590 410 260 680 540 430 Exercise 5-7 Cost behavior estimation- scatter diagram and high-low Felix & Co, reports the following information about its sales and cost of sales. Draw an estimate cost behavior using a scatter diagram, and compute fixed costs and variable costs per unit sold. The high-low method to estimate the fixed and variable components of the cost of sales. Units Sold Cost of Sales Units Sold Period Cost of Sales Period 0 400 800 1.200 $2,500 3,100 3.700 4,300 4,900 2.000 2.400 2.800 3,200 3,600 5,500 6.100 6,700 7,300 7.900 1.600 Exercise 5-8A Measurement of cost behavior using regression P1 Refer to the information from Exercise 5-7. Use spreadsheet software to use ordinary least squares topo sion to estimate the cost equation, including fixed and variable cost amounts. Exercise 5-9 Contribution margin A jeans maker is designing a new line of jeans called the Slims. The jeans will sell for $205 per per cost $164 per pair in variable costs to make. (1) Compute the contribution margin per pair.com contribution margin ratio. (3) Describe what the contribution margin ratio reveals about this new s about this new jeansine
