Answer: The options are given below:
A. $18.00 
B. $1,036.80 
C. $2.00 
D. $7.20 
E. $64.00
The correct option is D. $7.20
Explanation: 
From the question above, we were given: 
Annual demand = 100,000 units
Production = 4 hour cycle
d = 400 per day (250 days per year)
p = 4000 units per day
H = $40 per unit per year
Q = 200
We will be using the EPQ or Q formula to calculate the cost setup, thus:
Q = √(2Ds/H) . √(p/(p-d)
200=√(2x400x250s/40 . √(4000/(4000-400)
200=√5,000s . √1.11
By squaring both sides, we have:
40,000=5,550s
s=40,000/5,550
s=7.20
 
        
             
        
        
        
Answer: B. 1023, 1500, 2000} 
Explanation:
The Optimal solution should contain the set of quantities that would require the lowest no. of orders to achieve a discount in a class. 
1,023 is quite close to the lowest amount required of 1,000 in the 1,000 to 1,499 range. 
So are 1,500 and 2,000.
Option D can also work but it has too many order quantities and will inflate the price. 
The Optimal Solution therefore has to be from this option.

Answer:
b) a debit to Depletion Expense for $175,000
Explanation:
The computation of the depletion expense is shown below:
Depletion expense = (Purchase of mining rights × current year mined tons of ore) ÷ (expected harvested tons of ore)
= ($500,000 × 350,000 tons) ÷ (1,000,000 tons)
= $175,000
So the journal entry would be
Depletion Expense A/c Dr $175,000
            To Accumulated Depletion A/c $175,000
(Being the depletion expense is recorded)
