In class 2 ., The Model D is the Top/ favorite one having highest market return (24%) with lowest inventory cost ($79)
Explanation:
To Determine the value of the inventory at the lower of cost or market applied to each item in the inventory. simply we should calculate the profit margin for each category
Profit margin = (market value - cost price) = Profit ÷ cost price × 100
Class 1:
Model A
46 $116 $139
Profit margin = (139 - 116) = 23 ÷ 116 × 100 = 19.32%
Model B
49 243 239
Profit margin = (239 - 243)= -4 ÷ 243 × 100 = - 1.65% (loss)
Model C
43 233 252
Profit margin = (252 - 233) = 19 ÷ 233 × 100 = 8.15%
Class 2:
Model D
37 79 98
Profit margin = (98 - 79) = 19 ÷ 79 × 100 = 24%
Model E
6 151 130
Profit margin = (130 - 151) = - 21 ÷ 79 × 100 = -13.91 % (loss)
