When I was considering what to do with my $10,000 lottery winnings, my broker suggested that I invest half of it in gold, the va

lue of which was growing by 7% per year, and the other half in certificates of deposit (CDs), which were yielding 3% per year, compounded every 6 months. Assuming that these rates are sustained, how much will my investment be worth in 14 years? (Round your answer to the nearest cent.)

Answer: $20,478.78

Explanation:

In 14 years the investment will be,

Gold

10,000/2 = 5000

Then use the compound interest formula

5000 * (1+0.07)^ 14 = $12,892.67

For Certificates of Deposits.

Use the Compound interest formula

Rate and period are in years. Convert to semi annual basis.

3%/ 2 = 1.5%

14 * 2 = 28 periods

= 5000 ( 1+ 0.015) ^ 28

= $7,586.11

Add both

=$12,892.67 + $7,586.11

= $20,478.78

Determine the profit-maximizingLOADING... prices when a firm faces two markets where the inverse demand curves are Market A: p

Gala2k [10]

Answer:

Market A: $P_{A} = 20.00$

Market B: $P_{B} = 20.00$

Explanation:

Market A: $P_{A} = 80 - 2Q_{A}$ ........................ (1)

Market B: $P_{B} = 60 - 1Q_{B}$ ........................ (2)

MC = m = 20 ............................................... (3) for both markets

For Market A:

Profit maximizing price can be obtained when $P_{A} = m$

Therefore, we have:

$80 - 2Q_{A} = 20$

$80 - 20 = 2Q_{A}$

$60 = 2Q_{A}$

$Q_{A} = \frac{60}{2}$

$Q_{A} = 30$

Substituting 50 for $Q_{A}$ in equation (1), we have:

$P_{A} = 80 - 2(30)$

$P_{A} = 80 - 60$

$P_{A} = 20.00$

For Market B:

Profit maximizing price can be obtained when $P_{B} = m$

Therefore, we have:

$60 - 1Q_{B} = 20$

$60 - 20 = 1Q_{B}$

$40 = 1Q_{B}$

$Q_{B} = 40$

Substituting 80 for $Q_{B}$ in equation (2), we have:

$P_{B} = 60 - 1(40)$

$P_{B} = 20.00$

"Other things equal, when the price of a good rises, the quantity demanded of the good falls, and when the price falls, the quan

Daniel [21]

Answer:

d. All of the above are correct

Explanation:

Demand refers to the quantities of a product that buyers are willing to purchase at a given price over time. The relationship between demand and price is explained in the law of demand. The law asserts that everything else remaining constant, the demand for a product is indirectly related to its price.

The demand curve illustrates the relationship between price and demand for a service or product. The curve is downward sloping showing how the quantity demanded changes with changes in price. Most goods will behave as per the demand curve. However, inferior goods tend to behave differently. An increase in income reduces the demand for an inferior product.

The market equilibrium point for a product is reached when 11000 units are produced and sold at $24 per unit. The manufacturer w

iris [78.8K]

Answer:

Explanation:

Let the demand equation be P = X + YQ

at P = $24, Q = 11000units

24 = X + 11000Y.............equation 1

when P = $61, Q = 0units

61 = X

Substitute the value of X in equation 1

24 - X = 11000Y

Y = 24 - 61 /11000

Y = - 0.00336

hence demand equation ; P = X + YQ , P =61 - 0.00336Q

Similarly, let the supply equation be P = Z + wQ

at P = $24, Q = 11000units

24 = Z + 11000w....................equation 2

at P = $3, Q = 0

from equation P = Z + wQ, 3 = Z

hence Z = 3

Substitute the value of Z in equation 2

24 = Z + 11000w, but Z = 3

24 - 3/11000 = w

w = 0.00191

hence the supply equation becomes, P = 3 + 0.00191w

Answer:

The correct answer is letter "C": finding ways to lessen the harm on our environment.

Explanation:

Greening implies analyzing what factors of businesses are harmful to the environment where the firm carries out its operations so that impact can be reduced in favor of the natural atmosphere. To achieve that goal, companies take several steps such as <em>reducing power and water service usage, recycling </em>or <em>planting trees</em> in affected environments.
