Answer:
After 12 years the investment will be worth $5145.
Step-by-step explanation:
The formula used for compounded interest is:
A = P(1+r/n)^nt
where,
A = future value
P = Principal Amount
r = interest rate
n = no of times interest is compounded
t = time
In the question given:
A=?
P = $2100
r = 7.75% or 0.0775
n = 1
t= 12
A= 2100*(1+0.0775/1)^1*12
A= 2100 *(1+0.0775)^12
A= 2100 *(1.0775)^12
A= 2100 * 2.45
A= 5145
So, after 12 years the investment will be worth $5145.

-40
Step-by-step explanation:
at the moment your equation is x+40=0
you move the forty to the other side by subtraction and you get x= -40
If you need the answer using pi it’s also there
The nominal exchange rate (NER) is given by:
NER = RER × (foreign price / US price)
= 3/4 × ( 6 / 3)
= 3/2
In fact, with 1$ you can buy 1/3 of a US gallon, which corresponds to 1/4 of a foreigner gallon, which you would pay 3/2units.
Hence, the correct answer is a) <span>3/2 units of country A's currency per dollar.</span>
