Suppose that for a company manufacturing calculators, the cost, revenue, and profit equations are given by Start 1 By 3 Matrix

Nesterboy [21]

Answer:

Cost is Increasing at a rate of 20,000 per week
Revenue is decreasing at a rate of 100,000 per week
Profit is decreasing at a rate of 120,000 per week

Step-by-step explanation:

The cost, revenue, and profit equations for a company manufacturing calculators are given below:

Cost, C=90000+40x
Revenue, $R=200x-\frac{x^2}{20}$
Profit = R - C

$\frac{dx}{dt} =500\\$ When Production output x=4000

<u />

<u>Change in Cost</u>

Cost, C=90000+40x

$\frac{dC}{dt} =40\frac{dx}{dt}=40*500\\\frac{dC}{dt}=20,000$

<u>Change in Revenue</u>

$\frac{dR}{dt} =200\frac{dx}{dt}-\frac{x}{10}\frac{dx}{dt}\\=200*500-\frac{4000}{10}*500\\\frac{dR}{dt} =-100,000$

<u>Change in Profit</u>

$\frac{dP}{dt} =\frac{dR}{dt}-\frac{dC}{dt}\\=-100,000-20,000\\\frac{dP}{dt}=-120,000$

Therefore, when production output is 4000 and increasing at a rate of 500 calculators per week,

Cost is Increasing at a rate of 20,000 per week
Revenue is decreasing at a rate of 100,000 per week
Profit is decreasing at a rate of 120,000 per week

The actual income for this month has been reduced by $200. How can this budget be modified so there will be a positive actual ne

frozen [14]

To give a positive actual net income, the budget can be modified by reducing the amount spent on food and clothes, thereby reducing overall expenses to have the maximum amount of money for fixed expenses.

Option C is correct.

<h3>What is an actual net income?</h3>

In accounting, the actual net income is defined as an entity's income minus the costs of expenses on goods sold, depreciation, amortization, interest, and taxes.

To determine actual net income, start with gross income, which is the whole amount of money earned, and then deduct costs like taxes and interest payments.

To give a positive actual net income, the budget can be modified by reducing the amount spent on food and clothes, thereby reducing overall expenses to have the maximum amount of money for fixed expenses.
