The following data applies to questions 8 and 9: Jackson Co. had the following data for units produced and maintenance costs in each of the four quarters of their prior fiscal year: QUARTER 1: 10 units and $61 QUARTER 2: 13 units and $73 QUARTER 3: 9 units and $60 QUARTER 4: 12 units and $70 8. Using the Linear Regression Method, the slope of the budget line would be a. $3.00 b. $3.25 c. $3.50 d. $3.75 9. Using the Linear Regression Method and your answer from #8 above, calculate the fixed costs (Y- intercept) for the budget line a. $23.50 b. $28.75 c. $27.50 d. $25.75 10. The cost budget formula for a particular mixed cost is: $450+ ($1.85 x units). The total budgeted cost for a volume of 2,500 units would be: a. $4,875 b. $5,625 c. $4,625 d. $5,075
