A widely acknowledged problem with using the consumer price index as a measure of the cost of living is that it fails to account for the introduction of new goods.
More about consumer price index and its problem-
- A more accurate indicator of a nation's standard of living than per capita GDP is the consumer price index or CPI.
- It is based on the total cost of a fixed basket of goods and services purchased by an average customer in comparison to the cost of the same basket in a base year.
- The CPI can get a precise assessment of the cost of living by including a wide range of thousands of items and services with the set basket.
- It's crucial to keep in mind that the CPI is an index number or a percentage change from the base year rather than a monetary value like the GDP.
- Because CPI is based on a fixed basket of products, the CPI does not provide an entirely accurate measure of the cost of living, despite being a convenient approach to calculate the cost of living and the relative price level over time.
- The bias against substitution, the introduction of new products, and quality variations are three issues with the CPI that should be mentioned.

Answer: b. Net requirements
Explanation: Lot sizing is used to consolidate the calculated net requirements by a certain unit. It puts into consideration cost reduction and work efficiency. One method of lot sizing is the lot-for-lot where the net requirements occurring for each period are the order quantity which generates greater volume of orders with smaller quantities per order and inventory investment as a result of ordering exact requirements only. The order sizes for component parts are essentially determined directly from net requirements.
Answer: Total product cost per unit if 12,500 units = $13.
Explanation:
Given that,
Direct labor = $2
Direct material = $3
Variable overhead = $4
Total variable cost = $9
Fixed overhead ($50,000/10,000 units) = $5
Total product cost per unit = $14
Fixed Overhead at 12500 units = 
= $4
∴ Total product cost per unit if 12,500 units = Total variable cost per unit + Fixed Overhead at 12500 units
= 9 + 4
= $13
