A firm that stocks lightbulbs gathers the following information: Demand = 19,500 units per year, Ordering cost = $25 per order,

vredina [299]

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) $EOQ=\sqrt{ \frac{2\times D\times O}{C}}$

$EOQ=\sqrt{ \frac{2\times 19,500\times 25}{4}}$

= $\sqrt{\frac{975000}{4}}$

= $\sqrt{243,750}$

= 493.71044 ≈ 494

b) Annual holding cost = $4\times(\frac{Q}{2})$

= $4\times(\frac{494}{2})$

= 4 × 247

= 988

c) Annual ordering cost = $O\times(\frac{D}{Q} )$

= $25\times(\frac{19,500}{494} )$

= 25 × 39.47

= 986.75

AOQ = 494

Annual holding cost = 988

Annual ordering cost = 986.75

Steve subscribed to 10 podcasts for a total of 340 minutes. He used his two favorite tags, Hobbies & Recreation and Soliloqu

Gwar [14]

We let x and y be the number of Hobbies & Recreation and Soliloquies episodes that Steve subscribe. The system of linear equation that best represent the given above is,
x + y = 10
32x + 42y = 340
The values of x and y from the system are 8 and 2, respectively. Thus Steve subscribed to 8 Hobbies & Recreation and to 2 Soliloquies episodes.

Can someone please explain how to solve it ??

Alik [6]

if we look on one side, we already have one measurement. 4 cm. ok, that's the measurement on that side. look to the left now. that other side is also the same length, so we take that number and multiply it be 2 to get

$4 \times 2$

Wait! we're not done yet. look at the top. do you see the 3? well that's the width for the top of the rectangle. the bottom must be the same to right? so we get

$3 \times 2$

add both equations and you get

$(4 \times 2) + (3 \times 2)$

The answer is 14cm! Don't forget to label. ;)
