strojnjashka [21]

Answer:

$364.29

Explanation:

given,

Packing of crates per month (u)= 800

annual carrying cost of 35 percent of the purchase price per crate.

Ordering cost(S) = $ 28

D = 800 x 12 = 9600 crates/year

H = 0.35 P

H = 0.35 x $10

H = $3.50/crate per yr.

Present Total cost

= \dfrac{800}{2}\times 3.50 + \dfrac{9600}{800}\times 28

= 1400 + 336

= $ 1,736

Q_0 = \sqrt{\dfrac{2DS}{H}}

Q_0 = \sqrt{\dfrac{2\times 9600 \times 28}{3.50}}

Q_0 =\$ 391.92

Total cost at EOQ

= \dfrac{391.92}{2}\times 3.50 + \dfrac{9600}{391.92}\times 28

= 685.86 + 685.85

= $ 1,371.71

the firm save annually in ordering and carrying costs by using the EOQ

    = $ 1,736 - $ 1,371.71

    = $364.29
