Firlakuza [10]

Answer:

4w + 3c = $27

5w + c = $25.50

Step-by-step explanation:

Let us assume the w represent the cost of the sandwich

And, the c represent the cost of the bowl in a soup

Now the equations are

4w + 3c = $27

5w + c = $25.50

These two should be the equations that represent the situation

Every week, a car dealer ship sells at least 5 minivans. Write an inequality that represents this situation. Let c represent the
kvv77 [185]

Answer:

we conclude that an inequality 'c ≥ 5' denotes this situation.

Step-by-step explanation:

Given

  • A car dealer ship sells at least 5 minivans

When we talk about 'at least', it means we are talking about '≥' in terms of representing the 'at least' in inequality symbol.

For instance,

'm≥n' means 'm' is greater than or equal to 'n'.

It means 'm' is at least equal to 'n'.

Coming back to the question,

  • Let 'c' represent the number of minivans sold each week.

As the car dealer ship sells at least 5 minivans. so the

inequality will be: c ≥ 5

Thus, we conclude that an inequality 'c ≥ 5' denotes this situation.

Assume that the short-run cost and demand data given in the tables below confront a monopolistic competitor selling a given prod
Damm [24]

Given the information stated above, the firms maximum total profit will be $90. (Option A) See the explanation below.

<h3>What is Maximum Total Profit?</h3>

Maximum total profit is the highest profit

<h3>What is the calculation supporting the above answer?</h3>

It is to be noted that the attached excel spread sheet was computed using the following formulas:

MC(n) = TC(n) - TC(n-1)

MC(n) = marginal cost of nth unit

TC(n) = Total cost of n units of output

MC(1) = 40-25=15 and so on

Recall that

Total Revenue (TR) = Price * Quantity

that is:

TR = P * Q

Marginal Revenue of the nth unit of output  =

TR of the n unit of output - TR of the n-1 units of output.

MR(n)=TR(n)-TR(n-1)

MR(1)=55-0=55 and so on

Recall that Profit = TR  - TC

Thus,

Profit (0) = 0 - 25

= -25 and so on

By observation on the sheet, the maximum profit (that is highest profit attainable) is given as $90.

This corresponds with

  • the Quantity of 4 Unit
  • The Marginal Revenue of 25; and
  • Marginal Cost of 15.

Hence, option A is correct.

Which binomial is equivalent to (xy + z)(xy − z)?
Nata [24]

Answer:

x²y² - z²

Step-by-step explanation:

Note that

(xy + z)(xy - z) are the factors of a difference of squares

a² - b² = (a + b)(a - b)

here a = xy and b = z, thus

(xy + z)(xy - z) = (xy)² - z² = x²y² - z²
