A farmer plans to plant two crops, A and B. The cost of cultivating Crop A is $40/acre whereas the cost of cultivating Crop B is

$60/acre. The farmer has a maximum of $7400 available for land cultivation. Each acre of Crop A requires 20 labor-hours, and each acre of Crop B requires 25 labor-hours. The farmer has a maximum of 3300 labor-hours available. If she expects to make a profit of $170/acre on Crop A and $210/acre on Crop B, how many acres of each crop, x and y, respectively, should she plant in order to maximize her profit?

Answer:

We will plant 165 of Crop A

Explanation:

We will compare the marginal contribution for each crop:  A   B

Profit:                170.00     210

cost of cultivating:  40.00       60

CM per constrain      4.25            3.50

Crop A is better regarding cultivating cost.

Now we analize the labor hours:

Profit:                      170     210

Labor hours per crop 20       25

CM per constrain      8.50       8.40

Because Crop A is better at both constrain resource It will be better to plant only Crop A if possible. As assigning to Crop B will diminish the return on the scarce resourse.

We will see how much can we plant of Crop A

7400 / 40 = 185

3300 / 20 = 165

We will plant 165 of Crop A

which is the maximun we can plant at the given labor hours.

If staff salaries were $44,000/month last year, and the yearly cost increase from last year to this year $108,000, what is the m
andre [41]

Answer:

The monthly labor cost this year=$53,000

Explanation:

<em>Step 1: Determine yearly cost of labor last year</em>

T=C×N

where;

T=total cost of labor last year

C=labor cost per month

N=number of months in a year

In our case;

T=unknown, to be determined

C=$44,000 per month

N=12 months

Replacing;

T=(44,000×12)=$528,000

<em>Step 2: Determine yearly cost of labor this year</em>

This years cost of labor can be expressed as;

Y=T+I

where;

Y=this year's labor cost

T=last years labor cost

I=the increase in cost from last year to this year

In our case;

Y=unknown to be determined

T=$528,000

I=$108,000

Replacing;

Y=(528,000+108,000)=$636,000

<em>Step 3: Determine monthly cost of labor for this year</em>

Monthly labor cost this year=this years labor cost/number of months in a year

where;

Monthly labor cost this year=unknown to be determined

this years labor cost=$636,000

number of months in a year=12

Replacing;

Monthly labor cost this year=(636,000/12)=$53,000

The monthly labor cost this year=$53,000

slamgirl [31]

Answer:

The correct answer is letter "C": They were excited about the video conference system.

Explanation:

In order to make sentences more professional and direct, they must be objective. It implies any point of view, perspective, comment, or any subjective piece of information should be deleted so the statement is unbiased. By doing this, we avoid exaggerations or misunderstandings from the author.

In the sentence:

  • <em>They were </em><u><em>totally</em></u><em> excited to be getting a new system. </em>

We should delete "totally" which is an individual perception of the author. Then:

  • <em>They were excited about the video conference system.</em>

<em />

Will be a more objective sentence.
