Answer:
The amount that has to be deposited today is $6205.63 
Explanation:
The given parameters are;
The annual interest rate for the first 5 years = 4 percent 
The annual interest rate for the next 4 years = 4.6 percent 
The annual interest rate for the final 8 years = 5.3 percent 
Let the amount deposited be X, we have;
X × (1 + 0.04)⁵ + X × (1 + 0.04)⁵×(1.046)⁴ + X × (1 + 0.04)⁵×(1.046)⁴ ×(1.053)⁸ = $30,250
X ((1.04)^5 + (1 + 0.04)^5×(1.046)^4 + (1 + 0.04)^5×(1.046)^4 ×(1.053)^8) = $30,250
X × 4.875 = $30,250 
X = $30,250/$4.875 = $6205.63 
The amount that has to be deposited today = $6205.63.
 
        
             
        
        
        
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.
