To check your understanding of row grading consider the foll

To check your understanding of row grading, consider the following example. Suppose your classmate Eileen has completed the following assignment and is confused about the score she received. The problem she attempted appears below: Quantity (Pairs per hour) Total Fixed Total Variable Average Average Total Total Cost ($ per hour) 120 210 270 315 380 475 630 Marginal Cost Cost Cost Variable Cost Cost ($ per pair) ( per hour) ($ per hour) ($ per pair) ($ per pair) 120 60 45 65 95 155 120 120 120 120 120 120 120 90 150 195 260 355 480 90 50 65 65 71 80 210 135 X 105 95 95 105 X 4 Eileen understands that she typed a wrong value in the first cell in the Marginal Cost column, but she is confident that all the values in the Average Total Cost column are correct. Thus, she does not understand why she did not receive full credit for this table. Eileen asks you to help her understand why points were deducted. Upon reviewing Eileen\'s work, which of the following reasons explain Eileen\'s less-than-perfect score? Check all that apply Eileen made a mistake in the last row in the Variable Cost column Eileen made a mistake in the last row in the Average Total Cost column Eileen made a mistake in the third row in the Average Variable Cost column Eileen made a mistake in the third row in the Average Total Cost column The Marginal Cost column is graded by cell, whereas the rest of the table uses row grading. The maximum score for the row-graded part of the table is points for this part of the table Given the grading feedback, Eileen should expect to receive

Solution

Eileen has made one mistake \"The Last row in the variable cost column.\"

The real value for the last row of the variable cost column should be 510. Eileen has written 480 instead of 510 and the next value which will be affected by this change will be average variable cost last row it will change to 85 instead of 80.

(I have no idea how many marks she should get from this table, that must have been given by your teacher, How much marks she will allot for the correct answer and how much she will deduct for the wrong ones)
