A chain-saw rental firm charges $21 per day or fraction of a day to rent a saw, plus a fixed fee of $9 for re-sharpening the blade. Additional portions of a day are considered to a be a full day's rental, so rounding upward to identify an entire rental period may be necessary. Let S(x) represent the cost of renting a saw for x days. Complete parts (a) through (m) below. A. Draw a line through each open circle. B. Draw a line through each closed circle. C. Find the cost of renting a saw for more than 2 days and less than or equal to 3 days and graph the amount. Do the same for all days and fractions of days. D. Find the total number of days someone could rent a saw for and end the y-axis at that point. Continue to graph functions until the maximum. (i) What is the independent value? A. S; the cost of renting a saw B. The fixed cost of re-sharpening the blade C. x; the number of full and partial days D. The number of saws that are rented per day
