Answer:
Step-by-step explanation:
Demand = 19,500 units per year (D)
Ordering cost = $25 per order (O)
Holding cost = $4 per unit per year (C)
a) 
    
    = 
    = 
    = 493.71044 ≈ 494
b) Annual holding cost = 
                                       = 
                                       = 4 × 247
                                       = 988
c) Annual ordering cost = 
                                        = 
                                        = 25 × 39.47
                                        = 986.75
AOQ = 494
Annual holding cost = 988
Annual ordering cost = 986.75
 
        
             
        
        
        
It is the difference between the third and the first quartile

The ladder makes 79.92 degrees of angle with the ground (Calculation: Cos A = 7/40 = 0.175 resulting A = ACos 0.175 = 79.92 degrees). This problem can be solved by using a simple trigonometry formula of Cosine which stated Cos A = Adjacent/Hypotenuse. The ladder length of 40 feet is the hypotenuse side of the triangle and the 7 feet distance between the ladder's foot and the wall is the adjacent side<span>. </span>
        
                    
             
        
        
        
3^0 if zero is an exponent then the answer would be 1.
