"The spot price of the market index is $900. A 3-month forward contract on this index is priced at $930. What is the profit or l
Mademuasel [1]

Answer:

$10 profit

Explanation:

In this question, we are asked to calculate the profit or loss to a short position.

Firstly, we identify that the spot price of market index is $900.

Now, a three months forward contract equals a value of $930.

Raising the index to $920 at the expiry date is obviously a profit to the short position.

To calculate the profit here, we simply subtract the index at expiry date from the three months forward contract.

Mathematically, this is equal to $930-$920 = $10 profit

A customer buys 100 shares of DEFF stock at $150 per share. During the first year of owning the stock, the customer receives $45
Vlad [161]

Answer:

The total return on investment for the holding period is 10.5%.

Explanation:

If the consumer bought 100 shares for a value of $ 150, obtaining after a year $ 450 total for dividends and seeing his shares go to a value of $ 161.25, to obtain the total return on investment we must perform the following calculations:

On the one hand, we have a return of $ 450 in dividends, which were paid by the total set of 100 shares, with which each share paid $ 4.50 in that concept.

In addition, we have the increase in the value of the shares, which went from $ 150 to $ 161.25, that is, an increase of $ 11.25 per share, which multiplied by the total of 100 shares gives a total sum of $ 1,125.

Thus, adding the dividends to the improvement in the value of the shares, we have a total profit of $ 1,575. Now, to determine the percentage of return that said sum represents, we must perform a cross multiplication:

15,000 = 100

1,575 = X

(1,575 x 100) / 15,000 = X

10.5 = X

So, the rate of return on this investment is 10.5% of the starting value.

A profit-maximizing firm will base its decision to hire workers on the additional costs and benefits of each worker. If the extr
tia_tia [17]

Answer:

The correct answer is total revenue; total cost.

Explanation:

Cost reduction is one of the most addressed issues in companies. They do it all the time since it is a permanent process. This is because it always seeks to improve the profitability of the company and, consequently, productivity. In other words, try to "do more with less", which is to produce more with what you have or produce the same with lower expenses. In both cases the objective is to reduce costs.

A company can reduce costs for many reasons: for a drop in sales, for lack of liquidity, for not having access to credit, etc. And when this happens, the cost cut occurs in the areas of human resources with the dismissal of personnel, the restructuring of the purchase processes, changes of suppliers, among other measures.

It is important to know what the current production process is and, if possible, redesign it, seeking to eliminate unnecessary steps, that is, to shorten the production processes. A long production line implies a greater number of workers, more work in the process and more time in product development. It also increases the possibility of errors in the process.

To make the cost reduction in your company even more efficient, you need to know each process deeply to detect unnecessary steps and help you reduce processes and / or procedures that in the medium or long term translate into cost reduction.
