Answer:
4.86%
Explanation:
Given that,
First-class postage for a 1-ounce envelope = 4 cents
On August 1, 2007
A first-class stamp for the same envelope cost = 41 cents
Period, n = 49 years





i = 1.0486 - 1
= 0.0486 or 4.86%
Therefore, the interest rate is 4.86%.
Answer:
65 firms will be in the industry at the new long run equilibrium
Explanation:
in the long run the P=ATC
quantity before the change is
200 = 1000-4Q
4Q = 800
Q= 200
each firm output = Q/number of firms = 200 / 50
q = 4
new quantity is
200 = 1240-4Q
4Q = 1040
Q = 260
number of firms=new Q/q
=260/4 = 65
the number of firms is 65 in the long run.
Answer:
r = 9.86%
Explanation:
The formula for calculating the future value of an invested amount yielding a compound interest is given by:

where:
FV = future value = $16,000
PV = present value = $10,000
r = interest rate = ?
n = number of compounding period per year = 1
t = time in years = 5
∴ 
dividing both sides by 10,000


to remove the power of 5, we have to take the 5th root of both sides:

Using your calculator:
1.09856 = 1 + r
∴ r = 1.09856 - 1 = 0.09856
r = 0.0986 = 9.86%
∴ r = 9.86%
Answer:
along a track in the same direction.
Explanation:
According to the law of supply, the price of the goods increases with an increase in the quantity of the goods supplied. Similarly, the price of the goods decreases with a decrease in the quantity of the goods supplied. This means that the price and quantity are directly proportional to each other. The price and quantity will move along a track in the same direction respectively.
