Obviously if the model wants to upgrade the kitchen, it should be done by either the landlord or a subcontractor. As he creates

the IP model, the landlord wants to leave the choice of whether to actually upgrade the kitchen up to the optimization algorithm. How should this constraint be written if he uses the following scheme for decision variables? 5 points
x1 = contractor works on wood floors x2 = landlord works on wood floorsx3 = contractor works on kitchen tile x4 = landlord on kitchen tilex5 = contractor works on back door x6 = landlord works on back doorx7 = contractor works on garage door x8 = landlord works on garage doorA) x3 + x4 ≤ 1B) x3 + x4 = 1C) x3 - x4 ≤ 1D) x3 - x4 = 1

Answer:

a. x3+x4<=1

Explanation:

We need a multiple choice constraint. Constraint x3+x4 <= 1 states that only one of the 2 options of landlord or contractor working on kitchen tiles can be used. (Assuming x3, x4 are binary variables)

Hence if x3 = 1, x4 is 0, and if x4=1, x3 becomes 0. Please note, there is no constraint in question specifying that kitchen tile has to be done. Hence, both x3 and x4 can be 0 depending on cost optimization, and x3+x4<=1 will still hold correct.

Finishing Touches has two classes of stock authorized: 8%, $10 par preferred, and $1 par value common. The following transaction
natita [175]

Answer:

FINISHING TOUCHES

Balance Sheet  December 31, 2015

(Stockholders’ Equity Section)

Stockholders’ equity:

Common stock  = $100,000

Preferred stock  =  $30,000

Treasury stock  = -$5,500

Additional paid-in capital  = $3,216,000

Total paid-in capital  = $3,340,500

Retained earnings  = $63,100

(Preferred stock  = -$,30,000)

Total stockholders’ equity = $3,373,600

Explanation:

a) 100,000 Common stock issued at $35 per share with $1 par is valued at $1 in the Common Stock section while the difference $34 $(35 - 1) is taken to the Additional paid-in capital at 100,000 x $34.

b) 3,000 Preferred Stock  issued at $11 per share with $10 par is valued at $10 in the Preferred Stock while the difference $1 $(11 - 10) is taken to the Additional paid-in capital at 3,000 x $1.

c) Treasury stock is the repurchase of stock by the company.  It is a contra account to the equity accounts.  It is therefore deducted from the equity section.  Two methods exist for its treatment: the cost method and the par value treatment.  We used the par value treatment.

This involves stating the par value movements in the Treasury stock while  the additional loss or additional gain is taken to the Additional Paid-in Capital section.

On the other hand, the cost method treats the cost of repurchase in the Treasury stock.

d) Additional Paid-in Capital (APIC) account records the above par value received.  It is also where the above par value is deducted for Treasury Stock.

e) Retained Earnings represent the net income after paying dividends to common stockholders and preferred stockholders.

f) To get the total stockholders' equity, the preferred stock is deducted.  Holders of preferred stock are not equity holders.

nalin [4]

Answer:

interest rate is 2.25 %

Explanation:

given data

sell bond = $715

bond matures =  15 years

redeem =  $1,000

solution

we apply here formula that is

amount = principal × (1+r)^{t}    ................1

here put value and we get

1000 = 715  × (1+r)^{15}

(1+r)^{15} = \frac{1000}{715}

solve it we get

r = 0.022617

so rate is 2.25 %
