Universal Mines Inc. operates three mines in West Virginia. The ore from each mine is separated into two grades before it is shi

pped. The daily production capacities of the three mines, as well as their daily operating costs, are as follows: c/day Mine High-grade Ore, Low-grade Ore, Operating Cost Tons/day Tons/day in $/day 20,000 22,000 18,000 Mine 11 Mine III Universal has committed itself to deliver 54 tons of high-grade order and 65 tons of low-grade ore by the end of the week. Universal can run its mines seven days a week if required. Determine the number of days each mine should be operated during the upcoming week if Universal Mines is to fulfill its commitment at the minimum total cost. Round the answers to two decimal places.
a. The number of days Mine I should operate = _________days
b. The number of days Mine Il should operate = _________days
c. The number of days Mine III should operate = _________days
d. The total cost of the operation for next week = $ ________

Answer:

this is a cost minimization problem, but it is missing some numbers, so I looked for similar questions (see attached PDF):

minimization equation = 20x₁ + 22x₂ + 18x₃ (costs per ton)

where:

x₁ = mine I

x₂ = mine II

x₃ = mine III

the constraints are:

4x₁ + 6x₂ + x₃ ≥ 54 (high grade ore)

4x₁ + 4x₂ + 6x₃ ≥ 65 (low grade ore)

x₁, x₂, x₃ ≤ 7 (only 7 days per week)  

using solver, the optimal solution is

2x₁, 7x₂, and 5x₃

a. The number of days Mine I should operate = <u>2 days </u>

b. The number of days Mine Il should operate = <u>7 days </u>

c. The number of days Mine III should operate = <u>5 days </u>

d. The total cost of the operation for next week = <u>$284,000</u>

why is allowance for doubtful accounts credited, instead of accounts receivable, when recording the adjusting entry for bad debt
alukav5142 [94]

The allowance for doubtful accounts credited, instead of accounts receivable when recording the adjusting entry for bad debts  Because accounts receivable is made up of numerous client accounts, it cannot be credited unless it is known which particular customer will not pay.

The provision for questionable accounts is referred to as a "counter asset" since it reduces the value of an asset, in this example, the accounts receivable. The compensation, often known as a doubtful account, is management's projection of the amount of accounts receivable that customers will not pay. Let's assume, using the aforementioned example, that on June 30 a business reports an accounts receivable debit balance of $1,000,000. The business predicts that $50,000 will not be converted into cash and expects some consumers won't be able to pay the full amount.

The following information relates to the Matthew Young Company.
zvonat [6]

Answer:

year 2016   $  68,400

year 2017   $   99,488

year 2018   $   97,076

year 2019   $ 109,704

year 2020  $  95,602

Explanation:

2016: year-base the nominal is the same as the ending

2017:

122,744 x 100/134 = 91,600

second layer:

91,600 - 68,400 = 23,200

ending inventory

base layer              68,400

23,200 x 134/100 = 31,088

total                       99,488

2018:

132,904 /1.48 = 89,800

89,800 - 68,400 = 21.400

21,400 x 1.34 = 28,676

68,400 + 28,676 = 97,076

2019:

150,920 / 1.54 = 98,000

98,000 - 68,400 = 29,600

29,600 - 21,400 = 8,200

<u>Layers</u>

68,400 x 100/100 =  68,400

21,400 x 134/100 =  28,676

 8,200 x 154/100 =<u>  12,628</u>

Ending Inv              109,704

2020:

141,920 / 1.60 = 88,700

88,700 - 68,400 = 20,300

<u>Layers:</u>

68,400 x 100/100 = 68,400

20,300 x 134/100 = <u> 27,202 </u>

Elite Apparel Inc. is considering two investment projects. The estimated net cash flows from each project are as follows:
zalisa [80]

Answer:

the cash payback period for both projects is 2 years

NPV for plant expansion = $304,707.24

NPV for  Retail Store Expansion = $309,744.41

retail store expansion has the greater NPV

Explanation:

Here is the full question for question 2

. Because of the timing of the receipt of the net cash flows, the

plant expansion

retail store expansion

has the higher net present value

Payback calculates the amount of time it takes to recover the amount invested in a project from it cumulative cash flows

Please check the attached image for a calculation of how the payback period was calculated.

Net present value is the present value of after tax cash flows from an investment less the amount invested.  

NPV can be calculated using a financial calculator

for Plant Expansion

Cash flow in year 0 = -900,000

Cash flow in year 1 = 450,000

Cash flow in year 2 = 450,000

Cash flow in year 3 = 340,000

Cash flow in year 4 = 280,000

Cash flow in year 5 = 180,000

I = 15%

NPV = $304,707.24

For retail store expansion

Cash flow in year 0 = -900,000

Cash flow in year 1 = 500,000

Cash flow in year 2 = 400,000

Cash flow in year 3 = 350,000

Cash flow in year 4 = 250,000

Cash flow in year 5 = 200,000

I = 15%

NPV = $309,744.41

retail store expansion has the greater NPV

To find the NPV using a financial calculator:

1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.

2. after inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.  

3. Press compute
