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.

You rented space for a kiosk at the mall last year for the holiday season for $750. This year they increased it to $825. What is
bekas [8.4K]

Answer:

10%

Explanation:

Cost of kiosk last year = $750

Cost of kiosk this year = $825

Percentage increase = $825-$750 / $750 * 100

Percentage increase = $75 / $750 * 100

Percentage increase = 10%

So the percentage increase in the cost of rent is 10%.

"Ginny sells bottled water from a small stand by the beach. On the last day of summer vacation, many people are on the beach, an
konstantin123 [22]

Answer:

Explanation:

Once out of Ginny sight, Alex faces a dilemma: Work very hard (put in all effort) or shirk (put in little effort). If he works hard, he'll sell enough water to generate $90 in earnings (not including his personal cost). If he shirks, he'll only generate $50 in earnings. After the end of the work, he'll split his earnings with Ginny and also get half of what she earns at her stand. In terms of Eric's total utility, it is worse for him to work hard. Close A If Alex works hard, Alex and Sunita together earn $270 ($180 + $90), of which Eric keeps $120. However, he loses $20 worth of utility by working hard. Therefore his net earnings is $100. If he shirks, Eric and Ginny together earn $270 ($200+ $70), of which Eric will keeps $120, while his personal cost is zero. Therefore Alex, individually, is better off when he shirks. A more better way of finding the solution to the problem is to note that from Eric's view, the amount of money he gets from Ginny's sales from the stand does not rely on his own sales.

On January 1, 20Y8, Crabb &amp; Co. sold land to ASP, Inc. and accepted a two-year, $500,000 face value note as payment. 6% inte
jeka94

Answer:

1. Discount

2. $449,298.47

3. $369,298.47 gain

4. land reduces by $80,000, investment increases by $449,298.47, reserves increases by $369,298.47

Explanation:

Question 1

Using the formula below

Price=\frac{I_{1}}{1+r} +\frac{I_{2}+F}{(1+r)^{2}}

where

I = interest rate, which is 6% of 500,000 = 30,000

F = Face value, 500,000

r = borrowing cost = 12%

Therefore, the price of the note at the time it was used for payment was

Price=\frac{30,000}{1.12} +\frac{30,000+500,000}{(1.12)^{2}}

= $449,298.47.

As the price is lower than the face value of the note, the note was issued at a discount.

Question 2

The fair market value of the note is $449,298.47, the compute price in question 1.

Question 3

The gain/loss on the sale of the land

= sale price - purchase price

= $449,298.47 - 80,000

= $369,298.47.

Question 4

The transaction would affect Crabb & Co's balance sheet as follows.

<em>Asset side:</em>

land reduces by $80,000

investment increases by $449,298.47

<em>Equity & liabilities side:</em>

reserves increases by $369,298.47

Cash flow ________ be negative before debt and equity infusions and ________ be negative after them.
Eddi Din [679]

Cash flow can be negative before debt and equity injections and must not be negative afterward.

The income statement recognizes income and expenses when cash is incurred, not when cash is actually exchanged. A cash flow statement records cash inflows and outflows when they actually occur.

The present value method calculates the expected monetary gain or loss from a project by discounting all expected future cash inflows and outflows to date using the hurdle rate.

Accounting receipts are pure receipts - expenses = receipts; cash flow is when cash actually changes hands, either coming in or going out. Recent cash flow should be used.
