Hello Sir, another one from me, please! This year the output is 5,000 units and the o/h cost is $31,000. Price index is164. Three years ago the output was 2,000 units and o/h $8,800. Price index was 132. Using high-low technique, what is variable cost per unit expressed in current year prices. Again, I don’t know how to get to the answer – $6.69. I went through the study materials and lectures but couldn’t work it out.. Thank you very much, Aiga
