Answer:
(i) $133.12
(ii) $297.6
(iii) $300.8
(iv) $301.6
Explanation:
From the compounding formula;
Future value = Present value 
where r is the rate, m is the number of payment per year, and n is the number of years.
Interest = future value - present value
Given that present value = $800, r = 8%, n = 4 years.
(i) annually,
m = 1, so that;
Future value = 800
= $933.12
Interest = $933.12 - $800
= $133.12
(ii) quarterly,
m = 3, so that;
Future value = 800
= 800(1.372)
= $1097.6
Interest = $1097.6 - $800
= $297.6
(iii) monthly,
m = 12, so that;
Future value = 800
= 800(1.376)
= $1100.8
Interest = $1100.8 - $800
= $300.8
(iv) weekly,
m = 54, so that;
Future value = 800
= 800(1.377)
= $1101.6
Interest = $1101.6 - $800
= $301.6
In the question, continuously should be annually.
Solution:
Applicable formula is;
A = P(1+r)^n
Where;
A = Total amount after 30 years = $9,110
P = Amount invested = $5,000
r = Annual interest rate in decimals
n = Number of years = 30
Substituting;
9110 = 5000(1+r)^30
9110/5000 = (1+r)^30
1.822 = (1+r)^30
Taking natural logs on both sides;
ln (1.822) = 30 ln (1+r)
0.5999 = 30 ln (1+r)
0.5999/30 = ln (1+r)
0.019998 = ln (1+r)
Taking exponents on both sides
e^0.019998 = 1+r
1.0202 = 1+r
r = 1.0202 -1 = 0.0202 =2.02%
Therefore, annual interest rate should be 2.02%.
Answer: purchase foreign currency in order to purchase a U.S. treasury bond.
Explanation:
Currency convertibility has to do with the degree in which the domestic currency of a particular country can be converted into the currency of another country.
Therefore, a citizen in a developing country with a currency policy of convertibility on the current account could engage in the purchase foreign currency in order to purchase a U.S. treasury bond.
