 Procurement  is the supply chain function that receives inputs from the demand plan to procure materials, equipment, and services.
 The process of organizing the many tasks necessary to create and distribute goods and services to a company's clients is known as supply chain management. The transfer of raw materials from the supplier to the producer to the final delivery to the customer is all included in the supply chain. Designing, farming, manufacturing, packaging, and transportation are a few examples of supply chain operations. A supply chain is the entire process of getting a finished good or service to the client. It may be necessary to obtain raw materials, convey them to the production facility, and then deliver the finished products to a customer.

Answer:
B) dividing the change in total cost by the change in output
Explanation:
Marginal cost(MC) is the cost incurred as a result of producing additional units of goods and services. It is calculated by dividing a change in total cost by a change in output.
That is,
Marginal cost(MC)= change in total cost(TC)/ change in output
Total cost(TC): This is the addition of fixed and variable cost in production.
Total cost(TC)= fixed cost (FC)+variable cost (VC)
Fixed cost (FC) are cost that doesn't change during the production process such as buildings, machineries and furniture.
Variable cost (VC) are cost that changes or are used up during production process such as raw materials.
 
        
                    
             
        
        
        
Answer:
=2.98%
Explanation:
Use CAPM to find the required return of the stock;
CAPM: r = risk free + beta(market return - risk free)
risk free = 4.5% or 0.045 as a decimal
beta = -0.4
market return = 8.3% or 0.083 as a decimal
Next, plug in the numbers into the CAPM formula;
r = 0.045 -0.4(0.083 - 0.045)
r = 0.045 -0.0152
r = 0.0298 or 2.98%
Therefore the required return is 2.98%
 
        
             
        
        
        
Answer:
The concept of equivalence, also known as economic equivalence, describes the reduction of a series of cash inflows (benefits) and cash outflows (costs) to a single point in time, using a single interest rate, which enables the cash flows to be compared or equated.  This implies that while the amounts and timing of the cash flows (both inflows and outflows) may differ, an appropriate interest rate, factoring in the time value of money, will cause one set to be equal to the other.  Therefore, to establish economic equivalence, series of cash flows that occur at different points in time must be equalized using a single interest rate through present value calculations.
 
Explanation:
The concept of equivalence describes a combination of a single interest rate and the idea of the time value of money.  This combination helps to determine the different amounts of money at different points in time that are equal in economic value, such that a person would not hesitate to trade one for the other.
For example, if the interest rate is 10% in Year 1 and in Year 2 and you are to be paid $1,000 in Year 1, it will not make any difference to you if you are paid $1,100 in Year 2.  This is because, given the prevailing interest rate of 10%, the value you receive in Year 1 and Year 2 are equivalent.
