Answer:

Explanation:

weight average = fraction of A X MW of A + fraction of B x MW of B  

Mixture 1  

1 / 3 x 100000 + 2/3 x 400000 = 900000 / 3 = 300000

Mixture 2

2/3 x 100000 + 1/3 x 400000 = 600000 / 3 = 200000

Number average  

Mixture 1  

(1 / 100000 x 100000 + 2 / 400000 x 400000) / (1/100000 + 2/400000 )

= 3 x 400000 / 6  

= 200000

Mixture 2  

(2/100000 x 100000 + 1/400000 x 400000 )/ (2/100000 + 1 / 400000 )

3 x 400000 / 9  

=( 4/3 ) x 100000

We need to purchase to fullfil the inventory for this amount of units.

<u>Now we have to calculate each component:</u>

\left[\begin{array}{cccc}&denim material&zipper&thread\\Simple per unit&3&1&25\\Simple Quantity&106,5000&355,000&887,5000\\Fancy per unit&4.5&1&40\\Fancy Quantity&888,750&197,500&7,900,000\\Total Quantity&1,953,750&552,500&16,775,000\\Cost per unit&3.25&0.75&0.02\\Total Cost&6,349,687.5&414,375&335,500\\\end{array}\right]

Next, we multply the purchase requirement per amount per tpye of unit. Once we got total quantity me multiply by the cost.

Hello there!

Answer:

The working capital ratio would be 2.38:1

Explanation:

To find the working capital ratio of a company, we would need to get the total assets and liabilities and divide them.

Assets:

250,000+20,000+15,000= 285,000

You would have $285,000 in total assets

Liabilities:

45,000+75,000=120,000

You would have $120,000 in total liabilities.

Now, we would divide 285,000 by 120,000 in order to get your ratio.

Lets solve:

285,000 \div120,000= 2.375:1

If you need to round, you would round the 5 over to the 7 to turn it to 8.

Your ratio would be 2.38:1

2.38:1 would be the CORRECT answer.
