Which Calculation Method is used to calculate a benefit structure for units with different earnings per unit, particularly for a total quantity of 150 units?

The Calculation Method referred to as "Stepped" is the correct choice for determining a benefit structure for units that have varying earnings per unit, especially when dealing with a total quantity of units, like 150 in this case.

The "Stepped" calculation method is particularly effective in scenarios where different ranges of units can be invested in at different rates. For instance, with this method, each segment of units can be assigned a specific rate of earnings, allowing for a structured increment in benefits as more units are considered. This is especially useful in manufacturing contexts where bulk quantities might have tiered pricing models, enabling businesses to maximize their revenue based on the quantity sold or produced.

For total quantities, such as 150 units, the "Stepped" approach allows for a well-defined calculation that can handle the variations and provide insights into earnings across different thresholds of unit sales. This method is commonly utilized to incentivize larger purchases or productions by applying different rates as certain volume thresholds are crossed.

The other methods might not provide the right fit for calculating benefits under multiple unit earnings because they typically do not handle tiered structures effectively. Each has its own primary function that does not align with the need for a graduated approach to earnings based on quantity, thus reinforcing
