Profit is maximized when Q = 4 and P = $40, with maximum profit = $90.

<u>Explanation:</u>

(a)  (i) Marginal cost (MC) = Change in Total cost (TC) by Change in output (Q)

(ii) Total revenue (TR) = Price (P) into Q

(iii) Marginal revenue (MR) = Change in TR by Change in Q

(iv) Profit = TR - TC

Therefore:

Q  TC  MC  P  TR  MR  PROFIT

0  25   60  0   -25

1  40  15  55  55  55  15

2  45  5  50  100  45  55

3  55  10  45  135  35  80

4  70  15  40  160  25  90

5  90  20  35  175  15  85

6  115  25  30  180  5  65

7  145  30  25  175  -5  30

8  180  35  20  160  -15  -20

9  220 40  15  135  -25  -85

10  265 45  10  100  -35  -165

When Q = 4, MR = $25 and MC = $15, so MR > MC. When Q = 5, MR = $15 and MC = $20, so MR < MC. Therefore,  

Profit is maximized when Q = 4 and P = $40, with maximum profit = $90.

(b)  In the long run, new firms will enter the market by being attracted by positive short run profit. Therefore in long run, demand for individual firm will decrease, price for individual firm will decrease and profit will decrease until each existing firm earns zero economic profit.

Andrew [12]

Answer:

$1,025.299

Explanation:

The formula for compound interest is

FV = PV × (1+r)^ n

Where Fv is the future value

Pv is the present value = $1000

r is interest rate = 1/2 %  or 0.5% per year

n is five years

interest is compounded quarterly,  

Interest per quarter = 0.5% /4 = 0.125%  which is 0.00125

n will be 5 years x 4 quarters = 20 periods

Fv= $1000 x (1 +0.00125)^20

Fv =$1000 x(1.00125)^20

Fv= $1000 x 1.025299

Fv = $1,025.299

A publisher reports that 55% of their readers own a particular make of car. a marketing executive wants to test the claim that t
Dominik [7]

Based on the percentage of readers who own a particular make of the car and the random sample, we can infer that there is sufficient evidence at a 0.02 level to support the executive claim.

<h3>What is the evidence to support the executive's claim?</h3>

The hypothesis is:

Null hypothesis : P = 0.55

Alternate hypothesis : P ≠ 0.55

We then need to find the test statistic:

= (Probability found by marketing executive - Probability from publisher) / √( (Probability from publisher x (1 - Probability from publisher))/ number of people sampled

= (0.46 - 0.55) / √(( 0.55 x ( 1 - 0.55)) / 200

= -2.56

Using this z value as the test statistic, perform a two-tailed test to show:

= P( Z < -2.56) + P(Z > 2.56)

= 0.0052 + 0.0052

= 0.0104

The p-value is 0.0104 which is less than the significance level of 0.02. This means that we reject the null hypothesis.

The Marketing executive was correct.

The current rates for an 80/20 mortgages are 4.15% for the first mortgages and 9.75% for the second mortgage. On a $200,000 30 y
olganol [36]

Answer: The actual rate of the mortgage is 5.27%.

Since we're taking two mortgages for a total of $200,000 for 30 years, we can find the actual rate of the mortgage by finding the weighted average of the two rates. The weights in this case will be the proportion of loan taken at each rate

We have

Rates       Weights      Rates * Weights

4.15            0.80     4.15 * 0.80 = 3.32

9.75             0.20    9.75 * 0.20 = 1.95      

Total                                             5.27%
