I am missing explanations for g-i and I need answers and explanations for l-o. Can someone please help?

13. Classifying Cost Behavior For each of the following situations, select the most appropriate cost behavior pattern (as shown in the illustrations following this problem) where the lines represent the cost behavior pattern, the vertical axis represents costs, the horizontal axis represents total volume, and the dots represent actual costs. Each pattern may be used more than once. Graphs for Mini Exercise 15-13 (2) (3) (I) (8) (4) (4) a. Variable costs per unit b. Total fixed costs c. Total mixed costs d. Average fixed costs per unit e. Total current manufacturing costs f. Average variable costs g. Total costs when employees are paid $15 per hour for the first 40 hours worked each week and \$20 for each additional hour h. Total costs when employees are paid $15 per hour and guaranteed a minimum weekly wage of $300 i. Total costs per day when a consultant is paid $200 per hour with a maximum daily fee of $1,000 j. Total variable costs k. Total costs for salaries of social workers where each social worker can handle a maximum of 25 cases l. A water bill where a flat fee of $800 is charged for the first 100,000 gallons and additional water costs $0.005 per gallon m. Total variable costs properly used to estimate step costs n. Total materials costs o. Rent on exhibit space at a convention a) Variable costs per unit Correct Pattern: Pattern No. 8 (It reflects the total variable cost at each volume level that can be used to calculate variable cost per unit) b) Total fixed costs Correct Pattern: Pattern No. 8 (It is fixed, and it does not change with the change in production level) c) Total mixed costs Correct Pattern: Pattern No. 11 (It starts with a fixed cost only when the volume is zero. Then, it grows upward) d) Fixed costs per unit Correct Pattern: Pattern No. 1 (It is highest when the volume is zero and then it comes down with an increase in volume.) e) Total current manufacturing costs Correct Pattern: Pattern No. 11 (It starts with a fixed cost only when the volume is zero. Then, it grows upward) f) Average variable costs Correct Pattern: Pattern No. 8 (It reflects the total variable cost at each volume level that can be used to calculate variable cost per unit) g) Total costs when employees are paid $15 per hour for the first 40 hours worked each week and $20 for each additional hour Correct Pattern: Pattern No. 7 h) Total costs when employees are paid $15 per hour and guaranteed a minimum weekly wage of $300 Correct Pattern: Pattern No. 5 i) Total costs per day when a consultant is paid $200 per hour with a maximum daily fee of $1,000 Correct Pattern: Pattern No. 2
