Answer:

a 1,560 units

b 780 units

c 390 units

d $18,720

e $9,360

Step-by-step explanation:

Given that;

Production = 292,000

Daily demand , d = 400

Annual demand , D = 400 × 365 = 146,000

Production rate , P = 292,000 ÷ 365 = 800

Set up cost , Cs = $100

Holding cost , Ch = $24

a. What is the production order quantity

= √2 * D * Cs / CH × (p / p - d)

= √ 2 * 146,000 * 100/24 × (800/800-400)

= √1216666.6667 × 2

= √2433333.3334

= 1559.91

=1,560 units approximated.

b. What is the maximum inventory on hand

= EPQ × [ 1 - (d÷p) ]

= 1,560 × [ 1 - (400 ÷ 800) ]

= 1,560 × 0.5

= 780 units

c. What is the average inventory

= Maximum inventory ÷ 2

= 780 ÷ 2

= 390 units

d. What are the total holding costs

= EOQ/2 * Holding cost

= 1,560/2 * 24

= 780 *24

= $18,720

e. What does it cost to manage the inventory

= Holding cost * (Maximum inventory ÷ 2)

= 24 * (780 ÷ 2)

= 24 * 390

= $9,360
